alright i have an older dell dimension xps t600r running windows xp. i got a new camcorder that allows me to upload my videos onto my computer. the videos uploaded fine, but they dont play correctly. when the vid plays, it plays a few frames and kind of just skips over everything. its really pathetic. i use quicktime 7.0 like the directions that came with the camcorder told me to. i thought a new vid card would do this trick because like i said, its an older computer, but after i installed a new and better video card, the clarity and graphics of the monitor were substantially better, but my videos still dont play! i can play videos on websites like youtube and stuff, but my videos dont work. i have all the updated media platers. what could be wrong? any suggestions are appreciated. -thanks
