Hi, I'm planning on buying a new DVD burner so I can burn Divx videos I have downloaded. The videos I have right now are 24 minutes each at around 175MB. I'd like to know how many of these files can fit on a single DVDR disc. Will I be able to control the file size when I encode them to Mpeg2? How many of these files would you recommend that I burn on a single disc and do I still have to merge the videos to a single file using virtualdub before actually burning it?
