I have a strange problem. Maybe you faced it already.
I had problems with my nvidia geforce 8600 card, I changed it for a 7300 one.
I have a correct DVI connection now.
Till I changed the card I did sereval installations .
MythTV worked but I could not use the CD/DVD drive which is the computer to watch DVD movies.
Then I have no optical drive in my menu and I can only watch DVD movies if I switch to KDE.
MythTV does not work. It worked in the installations I did before but this time I get errors about loading the #37 mythtv player and the #28 Disc Drive [apparently the dvd drive].
How can I fix it without re-installing everything?
Thank you for your help
