The Wrong Way To Copy SVCDs

The other day, I had temporary access to a feature-length film on two
SVCD's. I didn't have time to make disk copies, so I used Windows
Explorer to drag and drop the files onto my hard drive, thinking I
could just burn copies later. Wrong!

Now that I've read a little about how a SVCD works, I realize I should
have made an image of the disk. But it's too late. I don't have
access to the SVCD's any more.

So is there any way to recover the video from the files on my hard
drive? Here's what I have done so far:

My initial google searches indicated that ISOBuster would be able to
create a valid MPG file using its "Extract but filter only M2F2 Mpg
frames" option. Well, ISOBuster will only extract files from an
optical drive. I couldn't find any way to tell it to look at the
AVSEQ01.MPG files on my hard drive. So back to Google, which led me
to TMPGEnc.

I used the MPEG Tools option in TMPGEnc to de-multiplex the
AVSEQ01.MPG files. This appears to have created valid .M2V and .MP2
files. The .M2V plays fine in my software DVD player (Blaze), but of
course there is no audio with it. It does not play in Windows Media
Player. I just get a blank screen - probably because I don't have a
M2V plug-in for WMP. But the .MP2 audio stream plays in WMP. So I
can watch the video in one application, while listening to the audio
in another, occasionally synchronizing during the whole film.

This is a little cumbersome, so I want to put these files back
together to create a valid MPEG-1 or MPEG-2.

I used the MPEG Tools in TMPGEnc again to multiplex the files. I
tried creating each of the valid output formats, such as "MPEG-1
System", "MPEG-1 Video CD", "MPEG-2 Program", and "MPEG-2 SVCD". But
none of these files would play in WMP. The software DVD player would
attempt to play them, but none would play correctly. In some cases, I
would get a video that was about one third the original size, and the
rest of the screen was black. Sometimes, I would get the one third
size video while the remaining two thirds of the screen would flash
green or other colors. Sometimes, the whole screen was just a bunch
of green blocks. And none of these files that TMPGEnc created had
audio.

I also tried multiplexing with bbMPEG and got basically the same
results.

So am I just screwed? Is there something else I could try?

If all you want to do is watch the film .. then Windows Media Player
should be able to play the files just fine. No need to go thru all that
work .. unless you want to make SVCD's again.

Yup. That did it. Nero was able to handle the AVSEQ01.MPG files. Thanks.

Nope. When I tried to play it in WMP, i received "Windows Media
Player encountered an unknown error." I think this may work with a
regular VCD, but not with SVCD's. Fortunately, I was able to bring it
into Nero and burn a SVCD copy.
