Is it possible to get an .avi to DVD without lossing quality?

I doubt you'd be able to convert it without losing some type of quality. You'll just have to try it and see what you think about the quality of the DVD video.

The guides over at Doom9 and VideoHelp are a great place to start.

How big is the avi? Of course you can burn it to a DVD as an avi :)

If it's less than the size of the DVD, you can do a lossless compression avi->mpeg

Its 2 .avi files, both ~700MB. Why do I want it in mpeg format as opposed to avi format?

Unless you have a player like the Philips 642, you will not be able to view these movies on a DVD player, just in a PC.

The conversion will lose some quality, but if you the right settings you can get it to look better than VHS. More than likely it'll be good enough, since it the original files didnt cost you anything.

Well, a friend of mine used Canopus ProCoder to convert the original Star Wars Trilogy films (xVid format with AC3 sound, about 1,600 MB each, done from LD rips) into DVDs, and we've spent an entire afternoon trying to see if we lost any quality. We couldn't see any loss. My guess is that if you use a high enough bitrate when you encode to MPEG-2, at a bitrate clearly above what the original file has to offer, and you use the highest quality (longest) encoding, you should be able to get a resulting file of superb quality.

MPEG4 based codec bitrates are different than MPEG2 bitrates. The original divx (or xvid) file was probably encoded with a fairly high bitrate, being that its 2CD. Its hard to know without details. If they are two seperate movies then the quality would be worse, so you may not lose any perceived quality from the original divx. Compressed video being recompressed to another compressed format will always lose quality unless the quality of the original was poor to begin with.

But there are things you can do like noise reduction and changing the colors to mask the quality. It can still look good, but I don't think it'll look as good as the original compressed video.

This is 1 movie, 2 parts. Bladerunner Criterion Collection. I'm a BR fanatic, but don't have the $$ to afford a LD player plus buy the CC Edition on Ebay for $50. This edition is different than the Dir. Cut. I've looked for any kind of torrent for it, but have turned up nothing. I know on sn.org they have the SW Trilogy from the LD rips, but no luck on the Blade Runner.

Were you able to save the chapters in the Trilogy or did you have to recreate them in Canopus?
