I've been having some problems loading Youtube videos. Most videos that I load show up as black and white, with streaks of colour across them. Any help?

yea this is an easy one, PSPtube has a view codec bugs with different videos on some sites. if its balck and white etc this means the flv codec is slightly different to PSPtubes flv codec. its a common problem that they will probly will eventually sort out. by the way what version of Ultimate PSPtube do you run?
