ok, i have sort of asked this question before, but, before, i wanted to use tmpgenc, now i want to use virtualdub so that i can just encode it back to dv .avi; i would like to keep the quality of the dv by using virtual dub. in tmpgenc i just load the dv .avi and select source as 16:9 then select the output as 4:3, and it gives me letterbox. i want to load the dv avi in virtual dub, and change it to letterbox then save it, again, as a dv avi instead of mpeg. thanks
