More in general keep this in mind:
the 'movie' business is usually split in three steps:
1) Encoding (most of the times you'll do AVI --> MPEG, but you migth do MPEG (PAL) <--> MPEG (NTSC), ASF --> MPEG and so on )
2) Authoring (the process which transforms mpeg --> VCD/SVCD/DVD image)
3) Burning (often made toghether step 2), but not necessarily)
The MPEG types are:
MPEG-1 (VCD): 352x288/240 (PAL/NTSC) resolution, 1150 CBR (Constant Bit Rate) kbps
MPEG-2. For SVCD: 480x480/576 resolution, VBR (you set only the average; usually 1500 < bitrate < 2500 kbps)
For DVD: 720x480/576 resolution, VBR [as before, but the encoding type and the bitrange range is different: you could have a 1000-8000 range or a 1000-8000 Constant Quality (CQ) threshold]. Remember that you have to encode more pixels than SVCD , and the media type is a single/dual layer DVD (4.5/9 GB), not some CD-R (N*800 MB)
Finally, but not so important, the audio. (S)VCD have MPEG Layer 2 (MP2) @44.1 kHz audio. DVD usually have Dolby Surround (AC3) audio @48 kHz, even if DVD player also support MP2 audio.
For authoring you have many application. Few of them (DVD Lab) allows authoring (S)VCD movies on a DVD. Some of them (Nero, for example, which I don't like for this reason) wants a spacific type and tries to encode (badly) the input ovie into 720x480/576 form.
And remember: garbage in = garbage out. The most stupid question I hear (and, alas, I hear often) is 'AVI --> DVD'. Which result do you expect by putting 700 MB movie into a 5 (or 9 GB) media (apart the length of the movie which can if in it)!?!?!?? The quality of the output movie will never be larger than the input movie's. You can decrease the quality [encoding NTSC --> PAL putting, in TMPGenc, Settings___Video___Motion search precision = very low (fastest), or converting DVD --> VCD], but you can never increase it!
The rest of the story is long. You have to study a lot, to choose a good encoding aplication (TMPGenc is the simplest but is very slow for MPEG-2 encodings, Cinema Craft Encoder [CCE] is the fastest but is very hard to learn - and it is the most expensive!) and a nice authoring application [my favorites are VCDEasy for (S)VCDs and DVD Lab for DVDs].
There's lot of stuff to do...
