I want to burn VCD (my dvd doesnt support svcd) from some movies in avi-divx (and they're very good quality).
When im converting them in mpg (using the default ntsc video cd default template in tmpgenc) im loosing a lot of quality, the final .mpg is really fuzzy compare to the divx.
(i set the motion serach precision to the highest quality).
What settings or operation a need to do to optimize the quality?

It is VERY difficult given that you are moving from a more compressed source to a less compressed final product. Every tiny flaw that is in your Divx movie is magnified...that being said...what are the main problems with your final mpeg? Is it fuzzy, blocky,colors wrong? Be more specific and someone can definitely help you out.

p.s. I just realized...loading up the template doesn't do all the settings for you....did you make sure that motion compensation was on HIGH? It makes a HUGE difference. -
I can usually preserve the quality of a good DivX with the TMPGEnc default template - just make sure two things - 1) set the motion search on highest!! and 2) on the Quantize Matrix tab select 'soften block noise' and change both values to 100
in old versions of TMPGEnc motion search between high and highest was probably no diff but since the lastest versions 2.0 and up it makes a big diff
also make sure your not changing the frame rate if you dont have to - if it's 25 fps select the PAL template and 29.97 choose the NTSC template -- also set your source aspect ratio to 1:1 -
one other thing - if your doing a lot of DivX conversions make sure to convert the audio to WAV first - saves you the headache of getting 75% done with a conversion and having TMPGEnc bomb out.

Wait, it's the audio file that causes those little error that crash the encode? The illeage floating points, or something like that? I thaught it was just the Divx file it's self. Gah... >.<

DJ_Izumi: could be either
take these precautions...
extract and convert the audio to WAV
rebuild and check the DivX with DivFix
http://www.divx-digest.com/software/divfix.html
that should cut down on those floating point errors
if all else fails convert the DivX with Panasonic it doesnt fail out on problem DivX files -
ok, I have found a procedure that works great with me.. I download the divx, open virtual dub. Set video to direct stream. Audio to full process, no compression on audio (PCM). then save avi. Open avi in TMPGEnc and encode it... works so good for me...

kimpan: you just used VirtualDub to convert the audio to WAV and rebuild the index (like DivFix) -- thats a good method to do it all in step though
