Check your codecs and data rates...

Catalyst prioritises audio so that you get no audio glitches when using audio playmodes. However, this may cause video 'glitching' if your content is not rendered in a sensible codec.

How many files are you trying to play?
what graphics card are you using?

dont use TH2G if you have a GT120 - it isnt good enough. - see other posts on the forum.

Do call if you need more help
