[linux-dvb] FW: "prebuffering pauses" new air2pccards(AirStar-HD5000)

[Todd]

I am wondering if anyone is seeing this...and if they know how to fix it.

Summary:  Using MythTV the Audio/video is choppy during playback (I can't 
tell if it is recorded this way or not)...in my errors I get a stream of 
prebuffering audio errors.  I think there might be something wrong with the 
capture/recording (and not playback) because:
1.  Both my myth frontends do this while maintaining <10% CPU/RAM/Disk IO.
2.  The Windows DSMyth drivers crash trying to play the recording.
3.  Recording keeps CPU load <.2...Disk/RAM/etc always < 10%
4.  Other capture cards work great in the same machine.
5.  Signal is strong and does not drop.

Other clues:  Channels with no audio (yes I have one; KiroDT2) have no 
pause...smooth video.  azap output:
tv:~# azap KIRO-DT
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 623028615 Hz
video pid 0x0031, audio pid 0x0034

FE_HAS_LOCK

FE_HAS_LOCK
status 1f | signal 94e2 | snr ffc0 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK
status 1f | signal 9496 | snr ffc3 | ber 00000000 | unc 00000000 | 
FE_HAS_LOCK

...And it stays that high.

Any help would be greatly appreciated.
