another Comcast head-end goes digital

Did you do anything to make it only process the DTV recordings, or were 
all your recording DTV at that point?

I wish there was a way in MythTV to specify a transcode command in a 
recording profile, seeing as they are tuner-specific. That way you could 
not only handle an audio transcode, but for the "Low Quality" profile 
you could transcode the video too, to save storage space. (Unlike the 
recording profiles for the PVR cards, the digital tuner cards have no 
options to set resolution and bitrate, as they just pass on whatever the 
broadcaster sends.)

I see MythTV supports a checkbox to enable transcoding on the recording 
profile, but I think that limits you to the built-in transcoder, which 
is useless if you need MPEG2.

Probably the mvpmc-users list. It has been posted there a few times.

Good to know. Others have reported audio time offsets when using that 
script to transcode the audio of digital TV.

I've used Roger's script a few times manually, and provided feedback to 
him, but it's overly complicated for what I need. His script attempts to 
take almost anything and figure out how to convert it to be mvpmc 
compatible. All I really should need is a simple ffmpeg command line to 
copy the video stream and reprocess the audio to MP2.
