It is possible to do this using something like TMPGenc.
There are guides at http://www.vcdhelp.com. Somebody
recently posted here that he tried to do this very thing
using TMPGenc and he had all kinds of weird problems, but it should be possible. Another alternative that might actually be better for you is to re-author (re-burn) the SVCD as a "VCD". Many people have been able to fake DVD players that don't officially support SVCD into playing these discs if they burn them as VCDs. There was a pretty good post a month or so ago in this forum on exactly how to do this. Sorry, I don't know where it is offhand, but hopefully a search can find it. If you burn your SVCDs as a VCD, you won't have to re-record them, but you will have to copy the video file off the disc and possible demux it and remux it. Some people have had issues in copying video files off of SVCD discs to hard drives though where the copy
would fail to complete. I think this may be due to
the CD-ROM drive timing out before the copy finishes.
I hope you don't have this problem, but if you do, it's
a bitch to deal with. Nero contains some drive tools
that might help you to change the timeout value of the
drive. I could never get that to work, so I had to
resort to using a Windows version of the Unix "tar"
command to copy the file. If you know Unix, you
can download the Cygwin toolkit and figure it out
(http://www.cygwin.com). If you don't know Unix,
you'll never figure out how to use tar correctly and
you'll have to find another way to deal with the
problem.

Converting SVCD to VCD is Pretty easy ,you jus have to rip the Mpeg files off the SVCD disk, they are usually in a Folder called Mpegav , then you Can try to change the header to a VCD header with the Mpeg tools in Tmpgenc But if your Player doesn"t play SVCD then it"s drive might not be fast enough to Play the SVCD bitrates even if you were able to fool the player into thinking the svcd was a VCD..Or you can allways Re-Encode it to VCD ,I would Use DVD2AVI to Make a D2V file and de-mux the audio then use the d2v file in Tmpgenc and encode it to M1V then mux the audio I demuxed with DVD2AVI to a Mpeg1/VCD file and burn it to Cd-R...

why on earth would you want to first create a d2v file - when tmpgenc have no problem importing the original mpg directly. It makes no difference to quality only to the time you need to spent on the project. Simply load the mpeg in tmpg and convert it to vcd or if you dont want to transcode the audio then remux first like you suggest but then only load the mpv file to tmpgenc.

DVD2AVI is only needed to create a d2v file when you cannot import the original vob or mpg file to an encoder. It does nothing in itself to enchance quality, it only fools encoders to think they are importing an avi instead of a vob/mpg file if they dont support importing these.

Why Would I make a D2V file ,Well Cuz Tmpgenc Is Crappy at Decodeing Mpeg2 files, and DVD2AVI is Faster at it, Ive Done many tests Useing the Ligos and Cyberlink Mpeg2 decoders that Tmpgenc Uses and DVD2AVI as the Decoder and You can get up to 30% Faster encodeing with Tmpgenc useing D2v Files as opposed to letting Tmpgenc Decode the file with the Ligos or Cyberlink Decoders..And if you load a Mpeg file into Tmpgenc you are re-encodeing the Audio when you don"t need to Cuz it is allready in the Correct Format For Mpeg and as every one Knows re-encodeing anything will Make you loose Quality..And The Overall Decodeing quality of DVD2AVI seems to Be supperior to the ones Tmpgenc uses I guess That is Why Most poeple use it for Encodeing VoB files.And Some Poeple Have Problems getting Tmpgenc to read Mpeg2 files Cuz they don"t have the Mpeg decoders Installed Properly or Just don"t have them at all...So this is Why Useing DVD2AVI is Faster and better..Try it I"m sure you will see a Good Encodeing speed Increase...

Like I said you could just remux first and only transcode the mpv file.

Its possible that encodingspeed could increase - I doubt it but I havent tried comparing so cant refuse that - but if so, any increase in encodingspeed would be eaten up by the time it takes to create the d2v file anyways. So basically I still think you are only adding another step to the process that is not really needed. I refuse to beleive there should be any difference in decodingquality between d2avi and the filters used by tmpgenc - simply because d2avi does not have any filters of its own and therefore use the exact same default directshowfilters to decode. If people think there is visible difference in the quality - its based on the placeboeffect and people are only fooling themselves

I like to allways know what Im talking about, hence I will be trying out your theory to make sure Im not wrong

I"m sory But DVD2AVI Does Have it"s own Mpeg2 decoder Built into the Program it is Simular to "Mpeg2Dec.dll" that AVISynth uses, if it didn"t you Wouldn"t be able to use The Program without Haveing Certain Mpeg2 Codecs installed on your System and I can use DVD2AVI without any Mpeg2 codecs installed becides the one that comes with DVD2AVI ..Cuz that is what DVD2AVI is a Mpeg Decoder.it does not use the same ones that Tmpgenc uses if it did you have to have something like Power DVD installed or the Ligos Decoders to run DVD2AVI Cuz that is what Tmpgenc uses to decode Mpeg2 files..Anyways Every one has there own way of doing things that works for them and This is what works best for me....cheers

1. Run TMPGEnc
2. Select File -> MPEG Tools
3. Select the Simple Multiplex tab
4. Browse the Video Input file and point to the mpg file
5. Select a new output file or directory (don't overwrite the original)
6. Select "MPEG-1 Video-CD" as mpeg "Type". Be sure to do this AFTER setting the input and output files as otherwise, the type may be reset to MPEG-2
7. Push the RUN button. (Ignore the buffer underflow error message at the end and press OK.) Exit TMPGEnc.
8. Use Nero to burn a VCD not as a SVCD. After dragging the mpg file to the VCD content window, a message will say that the file is invalid. Select the "Turn off standard compliance and continue" button and burn the VCD. DO NOT Re-encode the video file!

Good luck.

dodges strategy

I've never tried Dodges strategy, but its worth a try. Certainly if you reencode, what you'll end up with won't be pretty.
