I don't believe it's a low bitrate. I took a quick look at one of the
files in VLC and I think it said about 12 Mbps. I can double check but
I doubt that's it. WOW is actually pretty good about not
overcompressing things, and they've only got 2 channels (including
this one) on that multiplex. Plus, I don't seem to have any problems
with my SD channels, which are definitely much lower bitrates (with 6
or 7 channels to a multiplex)
I'm definitely not using any custom vdpau settings (just the VDPAU
normal profile). As far as the backend settings, I don't think I've
done anything odd, but this is a system that's been upgraded several
times, so who knows what config I might have set in the last 5 years.
I think the best bet will be for me to stop everything, setup a clean
alternate database (ex: mythconverg_test), point it to that, and see
what I get with that. It will probably be a few days before I get a
chance to do this.
