I have a mpeg2 file of 680 MB and converted it with tmpenc (mpegtools)
to a mpeg1 file via multiplexing
However after multiplexing the filesize becomes 225MB bigger which do not fit on one cdr.
Why does this happen, and can I prevent this?

What settings did you use in TmpgEnc? And to what file did you convert to(I think only possibility ist MPG1 isn't it)?

It's not very clear what you have done. Multiplexing a file (with audio) does not change the stream type from MPEG-2 to MPEG-1. From what you say, the extra 225Mb are probably the result of multiplexing a video stream (680Mb) with an audio stream at a high bitrate (225Mb).
If this is the case, a way to avoid re-encoding the video could be to re-encode the audio for a lower bitrate (e.g. 64kbps joint stereo). This should reduce the size of the audio file to the extent the multiplexed file may well fit on a 800MB CD-R
Again, the above comments are guesswork.The more I learn, the more I come to realize how little it is I know. -
What I hav done is the simple vcdheadertrick.
What I only just did is in mpegtools (tmpenc) clicked on multiplex
I loaded the svcd file. with type[mpeg-2 vbr]
Hereafter i selected type: mpeg-1 vcd and hit run
This resulted in a vcd file which was 200MB bigger?????
I used this manual
