    But I'm seeing a serious loss of sync between audio and video in Live TV mode. Sync starts off OK in Live TV mode but seems to get lost on channel change: in the last test I did audio lagged by about 8 seconds. My MVP is rev D3A and my Live TV quality is 6000 kbits/sec CBR. I'll continue to test as WAF allows.
    Thanks Luckerman, based on the feedback here I does seem like I have to clean out the buffers better when changing channels. Unfortunately now that my XP setup is history, I don't currently have live tv, to do much on this. At that bit rate it must be the audio buffer that needs to be cleared not just the demux.

    As for the WAF, originally I wasn't optimistic, but I think we might reach it after all the excellent feedback I've received here.

    Hi Martin,

    tested the alpha dongle from yesterday:
    -the buttons etc are a lot quicker now
    -Livetv seems to work but is very unstable, after pausing/restarting a few times it stops and reloads the mvpmc-screen. It'll take a ~minute to start the gbpvr-screen again.
    The following error was in the mvpgbpvr.exe.og:

    Code:
     
    2007-04-08 01:09:26.109 ERROR [11]    bij System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)

       bij GBPVR.xbb1566157f5f8b1f.xe75b6be209ce111f(Image x84901bd355736ef6)

    Also got a .Net error in the systemlogs after the first of those restarts, but only once .
    This was the error:

    Sometimes it seems that I have to restart the recservice to make it contact the mvp again.

    Code:
     
    Faulting application gbpvrrecordingservice.exe, version 1.0.2643.35874, stamp 0000003a, faulting module ntdll.dll, version 5.1.2600.2180, stamp 41109833, debug? 0, fault address 0x000106c3.
    -Recordings, music and foto's seem to play fine.

    But I think you are making a lot of progress, especially the speed is much better now.

    Thank Hans, there have been a few reports of problems with live tv this round and yesterday's alpha didn't do anything to improve the functionality. I am a bit surprised that mvpmc was actually able to crash the recording service, during my testing I regularily crash and close mvpmc and 99.12 has been extremely good.
    I also make sure that I run on extra service from config.exe so I can get back in.

    Did the new splash show ok at PAL resolution?

    I'll try that later/tomorrow.
    I have to add that the Youtube plugin and playing avi's (with ffmpeg on the fly) worked ok aswell.

    I think it looked ok, although I must admit I don't remember what to compare it with. Maybe I'll load the older dongle aswell, just to compare.

    If you have and NTSC/PAL TV you probably would't notice a difference.

    I checked the tv-manual: Pal, Secam and NTSC through scart. So that would probably explain why I never saw a problem in the 1st place.

    Other then confirming you are running 0404 I don't have a lot of solution.



    This is something I should be able to do. Can you confirm you are running 99.12

    Thanks

    Martin
    I am running 0404 and 99.12.
    I was using a playlist so I just tried it by selecting random from all tracks and it seemed to work fine - played 5 tracks in a row. Then I stopped it and selected the playlist and pressed random on that and it played the first two before giving up. The playlist works fine using a standard dongle.

    Cheers

    Thanks, it sounds like this hit the hole in my logic which I haven't been able figure out a solution for. When there isn't a recent keystroke but the screen saver isn't on or comes on for the first time there is the chance of a collision.

    I have uploaded a new dongle 0409 which hopefully clears the audio/video buffer problems in live tv. I have tested this on Vista Premium with the GBPVR medium and high quality settings and for me there is no sync issue.

    For those using the Hauppauge PVR150 with Vista I am having some LiveTV problems but this might not be an mvpmc issue. On some occassions instead of a 16k bitrate with enough length to start playing GBPVR identifies a 6500 bitrate with a zero length. If I get one of these the video does not start or a channge change fails. You can see this file setting if you run mvpmc from the command line.

    - The dongle I downloaded via you sticky page is dated 0409
    - As far as I could see nothing has improved in my setting, except the live tv image and sound seem to be in sync now. (see my post at the beginning of this thread)
    I now only tested LiveTV:
    - at startup the 'www.mvpmc.org' still scrolls a minute or so, until I see it change collor in blue. Finally I see the menu where I choose emulation. It almost immediately connects, and I see GBPVR menu (which has unacceptable flickr as mentioned before)
    - I switch to Live TV, image is fine. The following is switch to the next channel, which results in a short display of the menu, followed by a glimpse of a progress bar. Finally the screen stays black.
    - The following I did was powercycle the MVP. Choose emulation. quite often I have to go through two or three cycles of trying to connect here. In case I switched the MVP off for a prolonged time, reconnect in emulation is again almost immediate. So it looks like the GBPVR itself is very busy for some time to recover from the 'crash'.

    Sorry that I can't provide better news
