I'm PC and the clips I'm talking about are clips I've downloaded from here and they are all different formats. I downloaded and installed the AC3 filter and the AVI codec and they've helped a little but I'm still unable to burn and view most of the clips on TV. I've tried many different video converters but they either don't work or they diminish the video quality. I wish there was one single DVD burner that could just convert and burn everything all at once.
