 > To make matters more complicated dd-ing up to the first 90% or so of the
 file and playing the truncated file instead of the original file causes
 the failure to disappear.  It seems that Myth is choking on something in
 the last 10% or so of the file.  Unfortunately the 0.27 upgrade also
 killed off the ability to record new H264 files from my HDPVR (analog RGB
 component input with optical sound), so until I get that fixed I won't be
 able to provide a complete example file illustrating the problem.

 Update: Looks like the HDPVR (Myth?) cannot handle audio format changes.
 If an audio format change occurs (e.g. from a channel change) the
 recording becomes unplayable on *any* player.  This is new in 0.27 (it did
 not happen in 0.24 on identical hardware) and I guess I will need to open
 a new bug report for it.  I am working on getting test files together for
 this problem as well.

 Seems that the HDPVR didn't get much testing in 0.27?
