Thanks for the reply. I did run the frontend in a terminal and it did throw
h264 warnings about the frame size and saying that it's throwing frames out.
AFAIK Xvmc will not help with h264 encoded material.

Thanks Nick, I was kind of wondering that myself. Below is some of what I
see in my log (i'm sifting through it off and on today). There's usually a
few lines of these errors off and on, there's definitely large blocks on the
last error that seem to continue throughout playing the file.
[h264 @ 0x138db00]decode_slice_header error
[h264 @ 0xb9bb00]mmco: unref short failure
[h264 @ 0xb9bb00]number of reference frames exceeds max (probably corrupt
input), discarding one
I don't believe that the issue is corrupt data because I can play the HD
files just fine in other players (Xine and Mplayer specifically, I need to
try VLC yet). Has anyone ran into these errors before and more importantly
is there a fix?

<pre wrap="">Looks similar to errors you get with broadcast h264, some of those
streams are not handled yet by myth-0.21 because ffmpeg (which myth
uses an internal version of) has only recently started working with
this stuff.
you could try paul kendall's ppa repo [1], which has a patched version
of mythtv which will handle many of these errors. jean-yves avenard's
patched mythtv-0.21 also handles these streams, but you won't need his
version unless you have a vdpau capable card, which you haven't.

PS just realised pointing you to these repos is assuming you are using
mythbuntu, dunno whether there are equivalents for other distros.

PPS HD h264 is very processor intensive to decode. What cpu do you
have? Have you considered getting a vdpau capable video card?

<pre wrap="">I have a AMD 64 X2 5400+ (64 bit 2.8 Ghz Dual Core). I can get a vdpau card, I have a slot available in the machine even, it was just nice having it all in one. If it is the card then why can I play h264 stuff in other players? It is because they don't use ffmpeg for the decoding then? I also play h265 stuff through mythvideo which of course actually hands the playback off to Xine. I'm just curious on that one, if there's any more insight there :-) I will start looking for another card. Are there any recommendations for an Nvidia card with HDMI out that does vdpau?
Thanks Again,
Scott S.
