I use WinAVI to encode, and Nero to burn my movie files to DVD. Been working great up until the time I took the advice of a so-called movie burning guru, who advised me to install different codecs, as a lot of movie files i download now have different formats and versions. I have a virtual plethora of codecs and codec packs installed now. The problem is, now that I have all of these installed on my system, now I cant convert with winAVI, and that just makes me mad...lol can you, or anyone else, give me a straight and simple answer: what codecs and codec packs do I need in order to encode with winavi, and burn with nero, and play on my stand-alond dvd player like i used to? I am ready to uninstall every codec i have on here, with the exception of the quicktime and realplayer codecs that I know winavi requires. Any help....any one? Thanks, I am desparate...lol
