Hi to all, sorry for my poor english...

I want to make a SVCD from 3 large AVI files compressed with MATROX MJPEG (I have a Matrox Marvel G400 16Mb).
I would divide each file in smaller files, to associate (with NERO 5.5.5.1) each scene to a menu icon.

- How can I divide them?
- Which program's the best (and the faster) to do that?
- I must decompress and recompress the AVI files (MATROX MJPEG)?
- There will be a loss of quality during this operation?

Thank you
