I now use DVCD2SVCD ( http://www.dvd2dvd.org/ ) & when installing take the D2sroba option. The best encoder to use is Cinema Craft Encoder (version 2.50). However, this costs (unless you're into filesharing which I couldn't possibly suggest) but Quenc is free I believe.
I think there are guides on this site plus those on dvd2dvd.org that should help you using this package. It is not perhaps the easiest but I've been pleased with the results.
Regarding your writer, there are some on this site that would advise burning at 4x anyway & you only save a few minutes overall by burning at 8x.
