sorry to sound stupid (new to this )
if a dvd player does not play vcd , would it play dvdr films/multis
are the multi films just encoded into vcd format?? on dvdr?
thanks

I have just learned this m8.
multi`s are created when you re-encode the normal mpg`s into mpeg2 ( dvd compliant )
so if you have a film thats 5.0gb , if you rencode it into mpeg2 it will shrink it to about 2.3gb , so that way you can fit a few films on 1 dvd.
with tmpeg , you can choose what quality you want the dvd mpeg`s to be , that way , if you want to fit more than 2 films on a dvd , you would have to lose a bit of quality.
2 films are just perfect.
hope that helped m8

The above is of course not too accurate.
When you demux the VOB's of a DVD you will get a M2V (the actual video) file and 1 or more AC3 file (the audio streams) as well as subtitle files if that floats your boat.
Decent multi's or any downsampled DVD for that matter, are created by re-encoding the M2V at a lower bitrate BUT they will still be M2V. The fact of the matter is most commercial DVD's are way oversampled and re-encoding if it is done right will leaveyou with a M2V stream that the naked eye would be hard pressed to tell the difference by. If you know what settings to play around with you can decrease the size of the video file by approx 60% and still not lose any descernible quality with the DVD compliant resolutions still intact i.e 720x576 for Pal 720x40 for NTSC etc.
When the files are re-muxed with the audio and reauthored you will then get a FULLY DVD compliant film/multi. You shuldnt worry about VCD compatability as there is nowhere in the proceedure that anything remotely resembling a VCD comes into the equasion.
The only compatability issues you might have are regarding your players ability to play DVD-R. You can check this on the VCDhelp website.
