Disabling XvMC for DVD playback using internal player

Hi all,

This was mentioned a while back but I don't think anything came of it:
is there some setting/hack to disable XvMC when playing DVDs via the
internal player?

I need XvMC to play HDTV broadcast content, but when it is enabled
DVDs seem to play back at half speed with the audio repeatedly
dropping out. I can play DVDs with no problem on Xine, Ogle, MPlayer,
and on the internal player when XvMC is disabled. I know I can just
use Xine, but even after spending quite a while fiddling with the
configuration options it still doesn't integrate as seamlessly as the
internal player.

Thanks,
Ed.

From the wiki article:
http://www.mythtv.org/wiki/index.php/XvMC

Quote:
Use XvMC For HD Only

To use ffmpeg as your decoder for all content less than 720x*, insert
a row into settings where value = 'UseXvMCForHDOnly' and data = '1'
such as with the following SQL command:

INSERT INTO settings (value,data,hostname) VALUES ('UseXvMCForHDOnly',
'1', 'yourhost');

Naturally, substitute your frontend's host name for 'yourhost'. Be
sure your frontend has PreferredMPEG2Decoder set to Standard XvMC.

And in SVN trunk (and, when released, 0.21), there's support for
complete control over which rendering method is used for playback of
various types/resolutions of recordings. For now, though, the
0.20-fixes-compatible approach that Chad suggested is recommended. I'm
just mentioning that it will be officially supported in the future.

Thanks for that - I've enabled UseXvMCForHDOnly and it mostly works.
Unfortunately deinterlacing doesn't work (since my myth-box is set to
use bob-deinterlacing), and that the whole front-end crashes whenever
I go directly from an HDTV station to an SDTV station (haven't had a
chance to check the logs yet). A couple more questions if someone has
the time:

Will 0.21 allow me to use XvMC for all (SD and HD) TV content but not
for DVD playback?
Will 0.21 allow me to use one deinterlacer for TV and a different one for DVD?
In 0.20, is there a deinterlacer that's just as good as bob, but works
without XvMC?
