I used this program years ago on XP and from what I recall it was a good program. I was thinking of using it again but this time on Windows 7 x64. What I can't recall is if this program installs codecs all over the place on a system or just to the program files folder where the program is contained. I was going to fire it up in a VM to test the new version but I don't have the time yet. I just don't want codecs all over the f'n place and conflicts....or malware. My system is pretty basic, I only use WMP 12, that should give you an idea. Anybody who uses the program and has an opinion on it please chime in. Thanks.
