[mythtv-users] XvMC output not working

[Gavin Haslett]

I'm sincerely glad that worked. As I said I got somewhat flaky response
out of Xvmc until I enabled this option... Ever since then it's been
stable as a rock.

Another thing to make sure of is that your capture card (I'm presuming
you're using a Hauppauge or similar) is producing an actual valid Mpeg2
stream. If it's using RTJpeg/Mpeg4 then the Xvmc won't do the hardware
decode, it'll decode in software.

If you're using a BTTV based card, then I'm afraid I won't be much more
help as I'm not familiar with it. Isn't the default in Myth to use
RTJpeg with dumb capture cards??

I just actually realized I missed over this post.  I enabled this option
and restarted X, and to my surprise it worked again.  I'll see over the
next few days if the color OSD decides to make another cameo...

There are still issues that it gives me for X errors however, and i'm
not sure what those are caused by.
