[mythtv-users] Upgrading from pre-0.22 MythTV versions

[Igor Cicimov]

I upgraded to MythTV 0.23 about 2 weeks ago from 0.20 I've been running for
years. No problems at all. I also upgraded the ATI proprietary driver to
the latest version. The Ubuntu itself had 0.23-fixes in it's repositories
and I also added some ppa I found online for higher fixes version. All
running good. I decided to stick with the official Mythbuntu releases
though so not trying 0.24 or 0.25 since 0.23 does all I need. Except BD
playback ...
