Double VCD to single

[Groundsman]

Having found how to put a DVD on one VCD is it possible to redo Double VCDs to single 80min CD-R?

You could, but you would need to recode, which would mean a drop in quality because of the recode and a drop because you were lowering the bitrate to fit to one CD. Only trying it will tell if the quality is acceptable.

Yes, you should join and then reencode your VCD MPEG file using a PAL or NTSC VBR (x)VCD template. No quality drop at least in my opinion.
The picture quality is the same as your original vcd source and its playback is possible in many dvd players. See a list of compatible models at Kwag's site and use one of his templates but you may need some tweaks to fit the movie, for example increasing the CQ and due to the source that has a 352x240/288 resolution and its constant bitrate there is no need to encode the movie at 480/576 vertical resolution or a very high bitrate. VBR encoding and the GOP structure just do the great job.
A friendly comment to the admistrator:
This forum's been down 2 days a week in the last year and I think this is a game. Baldrick if you read the posts stop playing with the forum server or settings. we all need a forum to discuss and help each other and so many problems like this is not common. I don't know how to help you to resolve all these issues with your servers. What's the real problem?
I think it can't be money which you pay for the servers. I have no credit card but if I had I would be happy to donate if I knew this resolve the problem but I'm not sure.

that is not true..commercial vcd are alot higher quality than a home made vcd...plus when you reencode anything to a lesser quality/limited space storage.. u would lose alot of video and audio quality..
