There seems to be a bug in 2.20 and i notice that this version is still being released. Shouldn't 2.20 be taken off line? I had to reinstall 2.10 to get some of my movies to work or even to play a CD.
I just installed the bata 2.21, and noticed a bug fix for 2.20 in the installer. I think 2.20 should have a warning or just be removed completely from the net.
