I'm converting a lot of my videos to DVD using Winfast to copy, TMPGEnc to compress and convert and Ulead Movie Maker to write to DVD. Mostly this works well with very good quality. Using Ritek 4x DVD-R disks. Getting some errors of buffer underun which with the 106 should be "impossible". Now I know this sounds illogical but I've just wasted 3 disks trying to write Jurassic Park 2. It converts and compresses OK but fails with buffer underun, surely not the film? Or 2 consecutive disks ? Any clues guys? I've tried writing at 1 x with no luck either.
