[mythtv-users] No sound in VLC on Windows for 0.21 DVB recordings in .au

[Patrick Nichols]

Hi,

I've set up a test system for 0.21 to ensure my wife approval factor is 
maintained in the upgrade.  All is going swimmingly except for playing 
back recordings on windows (which happens about 20% of the playback time 
for my wife's recordings).

My setup is as follows:
* Mythtv 0.21 backend running on ubuntu 8.04 LTS regular ubuntu 0.21 
packages
* Upgraded to weekly mythbuntu 0.21 weekly fixes packages
* Located in Brisbane/Australia, recording free to air TV from the 
standard definition digital channels via DVB-T
* Two PCI DVB tuners (Leadtek DVB-1000T, Twinhan DTV thingo) both using 
multirec and allowing 4 streams per tuner to be recorded at once.
* Recordings/scheduling and everything works perfectly on the backend
* Playback of resulting recordings is patchy under VLC
* Playback of resulting recordings is patchy under Windows Media Player 11
* Problems with playback occurs for all channels

The playback problem for VLC (our preferred player) is no sound from 95% 
of recordings.  There are sometimes two sometimes one audio track.  
Sometimes it plays back on tracks with one.  I haven't found a recording 
where it will play back either of the dual audio track recordings 
sound.  Timing is right, no skips.  Seeking within the mpg is 
supported.  I've tried VLC 0.90 daily builds and 0.8.6f stable build.  
I've reset all configuration to default.  I've tried this on multiple 
machines for the same result.  Streaming under mythweb works with VLC.

The playback problem for Windows Media Player 11 is random jumpiness.  
Video will play fine with audio for all recordings however a half hour 
recording will play back in 5-10 minutes.  It will play fine for a while 
then skip a random amount of time and then continue to play back fine.  
This happens with all recordings.  Windows Media Player is also unable 
to seek through a recording.  Streaming under mythweb doesn't work for 
WMP11.

I've tried Dscaler.  It plays back recordings perfectly, however I'd 
prefer to use VLC due to the nice features and easy skip 
forward/backward key configuration.  Streaming isn't supported by Dscaler.

I don't have these problems with identical tuners recording from the 
same channels under the latest 0.20-fixes under ubuntu 6.06 on my 
"production" machine.  All recordings play back perfectly with all 
software on win32.

Any ideas?
