DVB-S EPG not working w/ Haupauge Nova-S

[newyankee]

Sub: The TS recording was made after tuning to the frequency in dvbstreamexplorer and getting a lock on the signal!

Shaky:
Look at config.exe.log:

To reproduce the error:

(1) cold start PC, start GBPVR config, select the DVB EPG capture source, then hit update EPG button.
Then save the log -> Error, no EPG update.
(2) start GBPVR config, select the DVB EPG capture source, then choose map channels to EPG, go to the preview/tuning list, select a channel from the first transponder/mux in the channel list, wait for preview picture to appear, then hit update EPG button.
Then save the log -> Update works, no error.

You can play this for each capture source...

In my case (1), only the first transponder (=mux) in each capture source is scanned. Then I get the error in the log and no EPG update. My gut feeling is that the EPG update starts to early, before the frequency is even locked. E.g. when I use live TV, I get about 5-20 seconds of "No signal" before the channel is on.

Hypothesis: It takes the diseqc switch a few milliseconds to switch, however, the first GBPVR tuning request will have passed by then. It appears that the tuner is not even properly initialized. If the EPG update starts right after that first tuning, GBPVR will try to update the EPG from any empty source. Thus, tuning manually first initializes the TV tuner and then updating works.

Is there any way to set a latency between tuning request and start of EPG update?

XMLTV EPG works like a charm, BTW. However, it is not available for all channels I use....

No, its not that.

I think it is some EPG data formatted in a way I hadnt encountered before, and GB-PVR is parsing it incorrectly leading to a crash.

I am looking for a temporary crutch to enable some kind of automatic DVB EPG update. Is there a way of tuning GBPVR via a commandline parameter to a specific channel number first and then call gbpvr.exe -OnlyUpdateEPG?

Thanks

Sorry, no there isnt.

[newyankee]

I am still updating the DVB EPG by going through config, selecting a channel from the first mux and then hit update.

Is there going to be a patch or hopefully a fix in the next release?

Thanks

To be honest, I dont know what was causing it, so no fix at this stage. I spent most of a day or so looking at it though.

If you can provide me an updated transport stream file, I'll take another look.

I'll do my best to get dvbstreamexplorer running again. The prog is an absolute pain in the neck.

I got dvbstreamexplorer working again. The new version 3 build 61 ist stable with BDA drivers. I will PM the download link.

Please take a look and let me know what else you might require.

Ok, downloading now.

Hmm, that new transport stream seemed to work fine and pulled in all the listings. I'm going to have work on the assumption that one of the changes I've made post v0.99.5 has corrected the issue, but I'm not sure what change it was specifically.
