Ok, I am making a compilation DVD of a Bands live performances - I've got about 20 videos of various lengths. I've opened them in virtual Dub and some are PAL and some are NTSC. The majority of them are PAL so I am going to convert all the videos to PAL Mpeg2 using TMPGENc and create a DVD using TMPGENc DVD author. Are there any implications of converting NTSC to PAL? Will I lose quality or experience skipping? Are there any alternatives?

thanks

Mark
