OK, that makes sense.

I looked around at transcode.cpp long enough to find the "copyvideo"
variable - it looks like the library classes have support for dumping
the raw streams out, but I can't seem to convince mythtranscode to do
it.  But it is looking more and more like what we're missing is glue.

Can anyone explain why transcode.cpp:353 requires fifodir to be NULL
before it'll set copyvideo to true?  It looks like that's what we're
all asking for.

Also, while experimenting with mythtranscode at the command line, I
noticed it reporting:
2004-08-18 17:39:10 Audio is 62ms ahead of video at # 1918
2004-08-18 17:39:10 Audio is 36ms ahead of video at # 1921
2004-08-18 17:39:10 Audio is 52ms ahead of video at # 1926
(...)

Does this support the glitch theory?  Looks like the wrong direction,
though, doesn't it?
