Hi Håkan
Download BitrateViewer (the free-of-charge one)
http://www.tecoltd.com/bitratev.htm
Analyse your SVCD's mpeg-file. If the resolution is 480X576 and the frame rate is 25 it is PAL. NTSC is 480x480, the frame rate is 29,97.
To copy the SVCD to your HD just copy the mpg-file.
To convert from one to another format don't use Nero but TMPGEnc (find the trial by Google).
Lycka till.
Regards, RHO
