I was afraid that this might be a hardware problem.  I've tried
turning on "Extra Audio buffering" and no change.  If it makes any
difference, the sound and the video studder together and not
independently (same rate, etc.)

I'm sorry - what is "SVN"?  Does the ./configure relate to a kernel recompile?

I don't see the "Preferred MPEG2 Decoder" on my system.  Does
./configure relate to a kernel recompile?

I've installed almost everything from scratch using yum and I would
hate to go manual unless absolutely necessary.  For me, it will be
much simpler to ditch an incompatable nvidia and sound card than to go
through another weekend of config hell - which I very likely would
face if I tried to modify the kernel.

On that point, is there a listing anywhere of sound and display video
cards that are known to work with myth and the HD3000, and hopefully
the playback settings in myth to use?
