Thanks for the hints! Maybe it was a bad idea, but I just copied all
the database files from my old system to the new one. Surprisingly, it
just worked "as is" - mysql picked up all the data and it seem to be Ok.
I then installed MythTV 0.22 from RPMFusion and ran mythtv-setup,
which upgraded my database to the new version.
And then mythbackend/mythfrontend just started normally.

Is it bad? Should I still drop the database and restart from scratch,
restoring only recorded programs?

Basically, my MythTV seem to work now. I only have a strange issue
displaying any video. Watching LiveTV is always fine, but watching
Recorded Programs gives me a black screen (the sound is there, I can
hear it). Even if I watch and record anything new, I can't watch it
again when I select it in "Watch Recordings" section...

It's also the same with mplayer when it is ran from mythfrontend.
Some movies do playback properly (with both, sound and video), while
others only have sound, and the black screen... Same video files are
always played back without any problems by mplayer if playback is
started directly from Gnome.

Any ideas on what could be wrong? Can it be related to any database

P.S. I have an Intel 915G integrated graphics on my
mythbackend/mythfrontend. I didn't have a chance to check it on
mythfrontend-only machine with NVidia 8600GT yet...

Best regards,
