I have downloaded a couple programs that convert rmvb to avi but each one has a diminish in quality which is the complete opposite of what I want. Is there any program that will convert rmvb to avi without losing any quality in sound or picture? The ones I have tried are winavi, cucusoft, imtoo and some others.
Free Video Converter - Any Video Converter Freeware - convert video free to AVI, MP4, WMV, MKV, MPEG, FLV, SWF, 3GP, DVD, MP3, WebM, iPad, Android, PSP, Tablet PC Any Video Converter is a good media converter that converts pretty much any video formats. You can try it and see.
Uh, hopefully in the 5+ years they have found a good converter. However in the off chance that they haven't I like MediaCoder MediaCoder - more than a universal audio/video transcoder - MediaCoder official website
