Hey mike, thanks for your respond
Oh, I didn't mean that kind of joining. Master Splitter and HjJoin are great programs for those too by the way.
Most pay sites doesn't have all their videos in full large video clips, so you have to dl them in several and smaller parts. Those video clips just had to join together. Otherwise there's a small pause between every single clip when you watch them with your player. Like joining many mp3 files together... must do if you have a concert for example
I removed my codec pack and got Koepi XviD 1.1.3. Maybe it's better use good single kodecs... I don't know. Next thing to check would be my graphic card. What else could possibly effect to handling videos? I guess the answer is just too simple to figure out... wouldn't be the first time
