You only have two choices. VCD and SVCD are for CD media. For DVD media, you can use DVD or LongDVD. I would experiment using both and see how much difference in quality you can see on playback. A standard SL DVD holds about 2 hours of video. The LongDVD option will likely squeeze more than 2 hours onto the disc, but quality loss will likely occur. So you will need to see for yourself if it is acceptable.
