I have 2 theories that I would liked answered from experience and not an assumption-

In TMPGenc, when you choose to encode into vcd standard, it sets everything standard of course. Now, keeping the mpeg-1 stream type at Video cd standard, I have noticed that you are able to decrease or increase the bitrate still and if changed dramatically, it will affect the file size.
MY QUESTION- if someone can only play standard vcds on their dvd player, would this be able for me to fit a little more onto an 80 min keeping vcd standard?


Next question-
In Nero- when selecting to burn an svcd, the first tab has the option to burn the svcd file in either MPEG2 dir or MPEGAV dir.
MY QUESTION- If someone could only play standard and non standard VCD, would it be possible when burning an svcd to change the folder to the vcd(MPEGAV) folder and see if it will trick the dvd player into thinking its a vcd?

The answer to your first question kinda walks a fine line. The vcd standard does call for 1150k cbr bitrate, but no encoder actually encodes at the exact same bitrate throughout. There will always be slight peaks and valleys in the bitrate levels. So all vcd compatible dvd players are made to accept at least a slight amount of variation in the bitrate levels for vcd. So most likely, if you adjust the bitrate levels very slightly, then it should still play on most vcd compatible dvd players, but technically it is still probably going outside of the vcd specs.

As for your next question, I think this procedure has been known to work in some cases, though its probably pretty rare.

ok man, thanks.

I'll do some tests on a dvd player than only supports standard movies and i'll post it up on here.
