Symptom is choppy audio/video. Sounds kind of like when people beat on their chests to impersonate a helicopter news update. Some channels seem _better_ than others.
I'm using 2 pchdtv (hd-3000). Watching free over the air ATSC. My backend is a 1.8 Athlon. Connected to 3.2 P4 via 100 Mbps LAN. With my old setup playback was flawless.
Things I changed... Kernel: from 2.6.10 to 2.6.11 mythtv: from .17 to .18 Driver: from pchdtv2.0 (v4l) to pchdtv2.0 (dvb)
If I change the dvb settings to record TS instead of PS seems to fix the video on all channels and the audio on _some_ channels. Some channels now totally lose their audio.
Using +/- to change audio streams has no effect.
Anyone else finding that the latest CVS and DVB loses audio very frequently? For me it appears as if it is auto switching audio streams.
Any ideas?

I set the "Use Hardware MPEG decoder" option in mythtv-setup to fix this problem. Before setting this I had the same problem with the 350 though the video plays back ok in mplayer and if you disable the use of the 350 for playback (which was how I watched a recording that was like this). I haven't tried switching to recording TS to see if that helps though.
