Forgive me if this is not the place to ask, if it isnt please direct me to the best place to find the answer.

I have been working on MythTV for a while now and I have to say I like its interface.

Recently, I switche to Nvidia's drivers rather than the included 'nv' driver in Fedora.

I can get everything working the way I want it, but I end up with blue lines when I run video overlay - on the top and on the left. It looks liek they arent more than a couple pixels each, but its annoying and Id like to get rid of them.

It almost feels like the video window is shifted down and to the right a little which reveals these blue lines?

I can replicate the problem with any video overlay, like mplayer, xine, MythTV (which also uses mplayer).

Any suggestions on how to fix this issue?

Thanks in advance...
