There is a new program out there for fiting 7.82gb dvd on dvd-r check this out http://www.afterdawn.com/software/video_software/dvd_rippers/dvd_shrink.cfm
it's great. very fast - takes about 30 mins. highly recommend this. only thing is choosing final size, sometimes not exactly that close to 4.37gb. and becareful, sometime you get to 4.38gb thinking it's okay but turns out file size just a bit over, so alway keep under 4.36gb.
