rbv5 nailed it, as i said in my second post in this thread what i actually need is dvr_ms to mpg, i just couldn't seem to find this but did find dvr_ms to wmv and figured i'd have to do a second translation to avi &/or mpg. all this is because mce forces you into dvr_ms - won't let you select the format for the video files it creates - stupid microsoft wanting to control all my digital content! my gmini 400 can't play dvr_ms, requires their own special format, but i've got an app that will create their format from avi or mpg. so, the need to convert dvr_ms to mgp. ideally lossless since i'll be going through a second conversion step to get to the gmini.
anyway, rbv5's trick worked, and lucky me, i googled the cyberlink filter he suggested (Cyberlink MPEG Muxer) and somebody at thegreenbutton made a script to do exactly what he said. fast and easy and it worked like a champ - output mpg looks great if there is any loss i can't see it. so mce is on my good list now, as is rbv5!
