I have a movie (Divx AVI) I have downloaded in 2 parts. It runs about 2 hrs. I ran each through Tmpgenc and since they are about the same size I allocated them 50% disk space each in the wizard to create 2 DVD Files that I would combine and burn in Tmpgenc DVD author. But in order to do that I had to use relatively low bitrates. Am I doing this correctly or is there another way of joining 2 parts of a file and making 1 while being able to keep a descent quality? Should I shrink them somehow with something like dvd95..etc

You should join them first. Use VirtualDub.
Open the first AVI.
Set the Audio and Video menus to 'Direct Stream Copy'.
From the File menu, select FILE | APPEND AVI Segment.
Select the second half of your AVI.
From the File menu, select FILE | SAVE AVI
Depending on the speed of your PC, it should take around 5 minutes to join them. You can encode the final AVI as you would any normal AVI.
If your prompted about VBRMP3 errors, you can handle those after joining your files. Ignore the error for the join process itself. If you did receive the MP3 error, you should, after joining your files, load the joined AVI, and extract the audio from the joined file as WAV (set the audio to full processing, and select FILE | SAVE WAV).
NOTE: If your AVI uses AC3 audio, you must repair it after joining the two files. Use AC3Fix to repair the AC3 file. It's a DOS program, but the syntax is easy.

If your target size is one DVD, what do you expect to gain by joining the AVIs? You still have to put the same amount (in time) of movie in the same amount (in bytes) of space, so the available max bit rate (=quality) will be the same...
However, you can join them like DJRumpy suggests (if they are encded to the same specs) but it wont adress your problem!
My post didn't address bitrate concerns. The subject asked only about joining the files
For 2 hours of video, on a DVD, with 224kbps audio, you can set your AVG bitrate to 4484Kbps, which is fine for just about any DVD. Just make sure you use Multipass VBR encoding, with your max set to at least 8000Kbps. For your min setting, I would suggest you set it to 0.
Use the bitrate calculator to plug in the exact length of your video. This will allow you to maximize your bitrate settings, without producing a fileset that is too large to fit onto your DVD.

Thanks for your help, I'll give it a try
I tried joining the two files in Virtual dub and I got "Cannot append segment, The audio streams have different sampling rates" Is there a workaround for this? the 2 files look identical except for their file sizes
...but in reality they aren't, obviously.
You only option is to demux audio and video of both files, then convert (and concatenate) both audio tracks to wav.
Load the video only avi's (load first, append second) then select WAV Audio under Audio. If the video at least is encoded to the same specs, you can then save (or frameserve) as one file.
There is one other possibility. You can append them together with AVISynth, but it is not newbie friendly. You do so, by converting both video segments to the same frame size, frame rate and audio format before splicing them together.
clip1 ++ clip2
I've broken the clip up into the long format to make it more readable, but you could combine all of this into one long line if you wanted to. The idea is to make each video the same in regards to frame size, frame rate, colorspace, and audio sample rate. I've done this before with disimilar video files. I haven't tried it with audio included, but it should work.
I would remove those items that aren't needed. For instance, if the frame size is the same for both, then you could remove the BicubicResize option.Impossible to see the future is. The Dark Side clouds everything...
