I updated to 2.2 followed the instructions perfectly and used the build.prop file to fix the market problem. I went to go playback a video i had taken before 2.2 and I get the error file cannot be played or displayed. Just to check I took another video after the 2.2 update and it took it just fine but when i go to play it back it gives the same error. Anybody else having this problem? Or does anybody have a fix for it? I am rooted but other than that and the 2.2 update thats the only major thing i have done to my droid x as far as i can think. Thanks.
