I still have not found any reliable resource which tells about the
limitations and real resolutions of a VCR. 

The best thing I have found by now is that the video bandwith of a VCR
is limited to 2MHz. Normal PAL has 5MHz. So calcualting back this would
mean that VCD "samples" every 0,125us one point, which is close to the
halfe amount of samples that PAL (every 0,067us) has. So that would mean
that VCR should be able to recognize and play back 360 different points
per video line. The other thing is how exact they sample every point (6
or 8 Bit). And how they store every point. I have no information about
that. And that is very important for the quality too. 

So still no final VCR reference, and guidlines.
But I think recording at a resolution of 720x576 (PAL) is charming for a
VCD, but not for a S-VCD. Recording at 352x576 or even 352x288 would be
something that is really worth thinking about, unless you have too much
free space on your HD's ;)

auf hoffentlich bald,
