The easier way is to buy a $100 standalone DVD recorder and run it to there. Doen't cut commercials, but it will cut your own time to a fraction of the amount you are spending. As far as file size, your DVD rendering program should allow you to choose from different levels of quailty, and you should be able to find one that creates a small enough file. On a DVD recorder, you also can choose quality levels (kind of like the old VCR SP LP and EP settings), and some (all?) recorders will tell you in advance how much time is available. Some even automatically set the recording quality to fit your specific program on a disk.
