VCDEasy / TMPGENC conversion problems

[Totta]

I have a downloaded concert in SVCD-format (bin/cue - 759MB) which I want to replace the audio on. No problem I thought, but soon I ran in to one strange problem that I hope someone here can tell me how to get past?

First I convert the bin-file to a MPG using VCDEasy, then I used TMPGENC to demux the sound and video. I then processed the sound, used TMPGENC to mux it back to a MPG and used VCDEasy to create the new cue/bin.

Now here's the strange part. I haven't changed any bitrates, any frequences or anything and STILL the bin-file is 110 MB bigger than before. Even stranger is that the new soundfile only is 27 BYTES bigger than the old one and since I haven't touched the M2V-file, where the heck is the extra 110 MB coming from?

I then did a small experiment. Using Nero, I imported the MPG file that VCDEasy exported and Nero said that it was 36:46 minutes long and would use 650 MB on a CDR.

Then I used TMPGENC and demuxed the MPG and immediately muxed it back to a new MPG. That one was also 36:46 minutes long but it would instead use 730MB on the CDR. On my harddrive the files are almost identical in size (766MB)

And of course, my biggest problem is that the new file is too big even to overburn on my CDR.

So, either someone can give me an explanation or a solution, or you can give me an alternative method of replacing the audio in a BIN-file.

Please?

The file is not too big to burn. Size is not as important if your making a video disk. Movie length is. Figure 10 minutes per megabyte, or about 800 megabytes will fit on an 80 Minute 700 MB CD.
