Paul,

Thanks for the assistance.

The audio file you referenced was available prior to making the 'Use
FIFO' change; it sounded fine.

However, I unchecked 'Use FIFO' ran again, and it failed at mplex...no
'stream0.ac3' was ever created.

The source is just one of my recordings; I have it set to, ' MPEG-2
Hardware Encoder' in Recording Profiles (I have a PVR-250).

Also, here is part of the mythlog...any suggestions?

Input #0, mpeg, from '/video/recordings/1054_20060526233000.mpg':
  Duration: 00:29:50.6, start: 0.333811, bitrate: 5096 kb/s
  Stream #0.0[0x1e0], 29.97 fps(r): Video: mpeg2video, yuv420p,
480x480, 6000 kb/s
  Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, stereo, 384 kb/s

Here is the latter part of mythburn.log after unselecting 'Use FIFO':
