Hi,
The current MythTv CVS version of MythTV has a stange problem with display on my Via M10K box which uses Via VLD XVMC hardware MPEG decode. The Via M10K box is a simple client with a separate server containg DVB cards.
Myth CVS after 2005.03.30 has this problem. MythTV CVS before 2005.02.20 is Ok.
If I watch an old recording, all is fine. If I watch live TV or a new recording the video and audio seems to have continuous gaps (about 4 per second) resulting in unwatchable/ unlistenable output. This results in a start/stop display. There are no special messages from mythfrontend. Watching using another system using software MPEG decode and Xv output all is fine.
Could some change to the DVB code have resulted in an MPEG stream that the Via MPEG hardware cannot decode correctly ?
Hi Terry,
I've finally updated the code on my epia to current cvs (I've been too busy doing the unichrome-pro drivers, that's my excuse anyway)
Anyhow I'm getting the same at the moment.
Changing to record TS reduces the problem slightly, but not much. Can you confirm if you're recording PS or TS.
Also I only see this on some transmissions, are you sure that all old recordings are fine and all new recordings are broken?
Most transmissions are just fine but a specific example is Eastenders which exibits this problem (hey I don't watch it ok!). Could it be some sort of problem with the type of sound stream?

Hi Ivor,
I am recording PS streams. You are right, it only seems to affect certain channels/transmissions. BBC1 (at the moment) is affected but BBC2/ITV1 is Ok.
I don't know if "all" my old recordings are fine (I have 400G of them !), but I think that they are. Also new recordings taken with the older 2004-02-20 software are fine.
I think the problem must lie with the DVB system, this had a major change in MythTv at this time. I note some mail-list entries about "Re: [mythtv] Re: DVB fix?", I wonder if this is related ? I would have thought that the DVB input system would just record the PS stream without mods, but maybe it plays around with it ?
