[Newbie help?] : Trouble with snippet of looping video?

[mbeveridge]

Hi,
Hope someone can help me with this, and that it's not too long. I've read forums (and googled), and have partially solved my initial problem, but have left ANSWER1 in case it is useful. Now I'm not sure what to try, and have no previous experience with this stuff. (Wiki hasn't been available today, but I didn't see any google links to it)

In summary, my problem is that using GB-PVR I have trouble after changing channels. I think that a consistent symptom is a snippet of looping video/audio, though the exact conditions seem to vary depending on whether it's a radio/non-radio channel, and whether I'm using TV/PC

Thanks, Mark



In more detail, here are some observations. It is "ANSWER2" that I need help with :

-----------------------------------------------------------
1. After selecting "LiveTV" from the menu, the screen is blank for a couple of seconds, then sometimes I get a 'blocky' picture for a couple of seconds, then it goes back to the menu. I get the same thing when selecting a programme from the EPG to play live, and when trying to replay recorded TV. I do get a small green&white "play" icon. [All of these are on the TV, rather than on PC, which worked ok though was sometimes jerky]

ANSWER1 : Needed to select the new mux that I installed (Cyberlink) from the dropdown menu in GB-PVR Configuration -> Misc (instead of Microsoft DVR-MS). Video is still blocky for the first 10 seconds or so


2. When selecting a radio station from the PC EPG, to play, I get an error window :
=========================
GBPVRRecordingService.exe
"Application has encountered a user-defined breakpoint
Process id=0x698(1688), Thread id=0xf5c(3932)"
=========================

I don't have a debugger, and clicking "Ignore" gave me a window saying :
=========================
"Error: Object reference not set to an instance of an object"
=========================

Selecting a 2nd subsequent radio station gave the same error. Selecting a subsequent TV station was ok (in the sense that the GB icon said it was recording LiveTV), but I had no video nor audio unless I restarted the GB-PVR application

Selecting a radio station from the TV EPG does work, though there seems to be an early snippet that loops and keeps interrupting. This seems to be from the current channel, unless I went there from a non-radio channel, in which case it is a 3 second snippet of the old channel (video + audio)

If I went to 2 radio channels and then a non-radio channel, then the application had to be closed :
=========================
"GBPVRRecordingService.exe has encountered a problem and needs to close. We are sorry for the inconvenience
Error signature :
szAppName : GBPVRRecordingService.exe
szAppVer : 1.0.2093.28460
szModName : MpgMux.ax
szModVer : 5.0.0.727
offset : 00018fcc"
=========================

...and in fact I had to reboot, because the GB icon still said it was recording LiveTV (radio), and the error message on the TV was :
=========================
"Failed to communicate with the recording service"
=========================

I also got the same GBPVRRecordingService.exe error when I went to 3 non-radio channels in succession, in which case there was a snippet of channel 2 looping (and channel 3 was never seen/ heard). However, when I did this via the PC EPG it seemed ok (but hard to test much, as there seem to be only 3 working non-radio channels in the EPG)

I did also get a "No tuners are available...etc" error window while I was testing, but can't remember the conditions that produced it, so am ignoring it at the moment

ANSWER2 :


(3. My EPG shows no programmes for a large bloc of channels. That seems odd. Doubt it's connected to the issue, but does mean I have few non-radio channels to test with)

(4. WinTV2000 no longer gives video nor audio, even if I shut down the GB-PVR server. I assume this is correct)
-----------------------------------------------------------



Installed (in this order) : WinTV2000; .NET 1.1; DirectX9.0; GB-PVR; (43-button IR remote fix?); Cyberlink mpgmux.ax from http://nolanparty.com/mediaportal.source...&start=15& . [Then also installed the 9.0b quartz.dll file from http://forums.snapstream.com/vb/showpost...stcount=26 ...but didn't notice any difference (prior to the fix in ANSWER1)]

Not installed : Hauppauge MVP software

Windows XP Pro SP2. Shuttle SD31P; Pentium4 3GHz; 1GB RAM. Hauppauge Media MVP (D3A). Hauppauge Nova-T USB2
External aerial in a good (analogue) terrestrial TV reception area

When I connect to the PC via laptop (over MS Remote Desktop Connection), I get the message "This system does not appear to support VMR9. Please try a different renderer" ...even though I have the same .NET and DirectX and quartz.dll software installed (see below)

The PC also has a (Slim Devices) Slimserver running on it, but stopping that doesn't seem to make any difference to my problem

My LAN connections are currently wired, but I intend to have a wireless (802.11g) link between the PC and MVP in future

Dont try to use any DVB radio stations. There is no current support for DVB radio in GB-PVR. If you try to use them, you'll get errors.

Sorry, thats a short answer to a long post, but I've got to get on a plane in a few mintes.

[mbeveridge]

Thanks. That was my plan from earlier, but I thought it may be a symptom of something else...

Did the "GBPVRRecordingService.exe error when I went to 3 non-radio channels in succession" ring any bells?

Cheers

There is lots errors that occur if you attempt to use DVB radio stations, and I'm sure this is probably just another one. I dont currently test anything DVB radio related, so I'm not fully aware of the specific problems you'll encounter.

[mbeveridge]

Thanks a lot

I've removed all the stations I can identify as radio, and when the EPG shows more than 3 I'll retest and report in the thread whether that fixed it

Cheers, Mark

Ok, I'm afraid that didn't solve my main problem. But it reduced the variety of symptoms, so maybe I can now be clearer

The error message I consistently get now is :
=========================
"GBPVRRecordingService.exe has encountered a problem and needs to close. We are sorry for the inconvenience
Error signature :
szAppName : GBPVRRecordingService.exe
szAppVer : 1.0.2093.28460
szModName : MpgMux.ax
szModVer : 5.0.0.727
offset : 00018fcc"
=========================

I use a Hauppauge MVP. I get the 2 to 3s video loop and error message, if I change channel using :

1. The "Ch" button
2. The EPG via the "Guide" button
3. The EPG via the "Menu" button

The 'crash' happens if total sequence of channels is >1 (ie. zero successful channel changes). The video loop is of the final few seconds from the 'previous' channel. [I had one early instance where I successfully changed channel once, using option "2." above, but couldn't reproduce that]. The selection of the initial channel was from "TV Guide", although I also tried a couple from "Live TV" and got the same result

I live in UK, and now have an almost complete (non-radio) EPG to test with (though where are the programmes for BBC3, BBC4 : should they show up on the same line as CBBC, CBeebies?). The testing above was done on "five", "BBC News 24", "CBBC"

NOTE : I do NOT seem to have the same problem on the PC. On that I had a successful sequence of 16 channels (and the problems after 16 seem channel-specific)

[Cyb]

I'm pretty sure BBC3/4 & CBBC/Cbeebies are the same two channels i.e CBBC/Cbeebies during the day and BBC3/4 in the evening.

[mbeveridge]

Cyb,
Thanks. I did hear that elsewhere, but it surprised me that my EPG only shows "This is CBBC!"/ "This is CBeebies!" as the evening programmes on those channels

Maybe if I rescan the channels in the evening they will be stored (by GB-PVR) as BBC3/ BBC4 instead, and that will make a difference to the EPG?

[Cyb]

I just remapped them as the tuning request for BBC3/4 in the "map channels to epg" section, I don't download epg data for cbbc or cbeebies.

[mbeveridge]

Sorry if I'm being thick. I still don't understand

Do you mean "Config" application -> Capture Sources -> Edit -> Map Digital Channels to EPG Channels ? ...Page headed "Digital Channel Mapping". When I rescan, there is no channel named BBC3/ BBC4. And in the list of channels with an "Enabled" check box next to them, I can't find a way to edit the "Channel Name"

Or do you mean "Config" application -> Capture Sources -> Edit ? ...Page headed "Edit Recording Source". In the row where Channel name="CBBC Channel" I can overtype in the "Tuning request" column, replacing "CBBC Channel" instances at the beginning and end with BBC3. But this doesn't seem to get saved. Is it what you mean?
