keep original screen size when converting?

[stbbish]

i am converting a SVCD into a VCD using tmpgenc and dvd2avi, but when i convert it the screen size of the VCD file I have made is much smaller than the size of the original SVCD screen. Is there a way of keeping the original screen size when converting? thanks, steve

If you change screen size it no-longer VCD....
VCD is MPEG1 352x240 29.97fps 1150kbps video and 224kbps audio
SVCD is MPEG2 480x480......
So you changed it by converting......Now if your machine (DVD Player) can play nonstandard VCD then get a modified template from the tools section here and burn non-standard VCD.... then you can set res to 480x480
