I Film all the football and basketball games for the high school and I make all the DVDs of the games every year. This year I am looking for a way to get more games on the discs with better quality as basketball has between 25 & 30 game seasons. I know how to get all the games on a couple of discs and all that and that it looks not very good that way. I use DVIO to get the video off my camcorder, TMPGEn to convert to mpeg and usually TMPGEnc DVD Author to make the DVDs, and then CloneDVD2, or DVD2One V2, once in a while DVD Shrink, to make them Fit on a single disc. Now what I'd really like some help on is why the hell when I use 1 of the programs to shrink down a regular store bought DVD they still look awesome? Those are 7-10 gigs before hand and you can rarely tell the difference. But when I shrink down my school DVDs they never look that good. They get that VCD kinda quality. Can someone please tell me if I'm doing something wrong here. And yes I know that if I make just and hour or so on a disc it would look great and all that. I really don't want to end up making a 20 disc set.
Thanx for any help.

well, for starters..the quality of the recording has a big effect on the bit rate manipulation for compression, an industry produced DVD has a high tolerance to bit rate manipulation because the source quality is much higher than what you can get from a production recorder. your going to have to experiment with your bit rate settings to get the maximum compression with acceptable viewing quality.

Have you tried to just encode once to the correct size in TMPGEnc rather than transcode again?

Yeah I guess your right on the quality being better to start. And yeah I've used TMPGEnc to get the correct size to start, but if you add to many to the disc the quality goes down. I guess I'll just have to make a bigger DVD set this year. Thanx all for the help.
