How to know which codecs are being used in making a VCD?

Hi guys  :
I'm new to this forum, so excuse me if i'm making dumb questions, but i'm trying to get information on how encoding video works.
So here's my question:
How can i know which codecs (audio & video) are being use converting AVI to VCD with TMPGEnc 4.0 Xpress or any other encoder?. Please, picture this: I use AVIcodec and GSpot information tools and they are telling me i have 5 different codecs for Div3 (MPEG-4 Low-Motion) in my system, which one will be used by TMPGEnc for doing its work???, is there any way to especify the one i prefer to use the way that i especify the prefered one for AVI conversion?
Well, thanks in advance and best regards to all of you

VCD is mpeg1, nothing to do with Divx.

Well, thanks anyway smok3    although i already know that, maybe i didn't express myself clearly but what i'd like to know is the way the whole conversion takes place, mostly the video conversion involved in making a VCD, lets assume AVI to VCD: the AVI needs to be decoded and then coded to MPEG 1 i guess, so how can i know which codec is being use by the program (TMPGEnc 4.0 Express or any other) to do this???, many times, specially when we install codec packs like Klite, AceMega, etc., would be 5 or 6 codecs in the system that could do the job, but we know that not all of them would bring good results.
Hope this time you can understand what i'm wanting to know.
Thanks again,
Best regards for you all guys

ways of doing it (in order of chaos):

1. change the fourCC of the file itself to the one you prefer (like divx to xvid)
(if using koepi xvid builds, there is aviC.exe which can do that)
2. unistall stuff you dont need, no you dont need divx3 in 2007, dont install codec packs in the first place (just my HO)
3. there are tools to change filter merits or disable/enable filters (you can also do some registry hacks by urself)
example dv vfw decoder switch:

pinnacle_dv_on.reg

Code: [Select]
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]
"VIDC.DVSD"="RALCodec.dll"


pinnacle_dv_off.reg
Code: [Select]
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]
"VIDC.DVSD"=-


4. there is a tool named graphedit which may give you some info on the directshow decoders (use file/render media file)
Whats interesting is that you can build different graphs and even playback the same file in sync using them;



5. if you check decoder info in virtualdub, then you can write a lil avisynth script using 'avisource=myfile.avi' and the filters used will be the same as in virtualdub (you can feed that script to the encoder)

Thanks smok3!!!  , definitively that's what i needed to know. I have the whole DivX Pro v6.6.1.4 package installed and registered on my PC and also ffdshow_beta3_rev1324_20070701_clsid, should i uninstall one of them??, i use FFDshow to have subtitle support in MainConcept MPEG Encoder, i know FFDshow package installs the DivX codecs, but will all AVIs be code/decode with only this package installed??
Sometimes when i'm not in a hurry i alternatively frameserve with AviSynth to TMPGEnc 4.0 XPress using the DirectShowSource internal filter in AviSynth to input a ''fake'' AVI to TXP4 that normally fails to do this by itself, also give me the chance to use the other filters in AviSynth and the subtitle support as well through FFDshow, there's a work around that can do the trick and it works perfectly for me giving very high quality MPEGs.
I would appreciate if you give me some advice 'bout what codecs should i have installed and if there any registry hack that allows me turn off/on VobSub, because sometimes i use Subresync to convert subtitles from one format to another and the subtitles support crash    in play/encode modes since a have FFDshow running too.
Well, thanks again!!!,
My best regards,
