Since i've done lots of video converting hear this and don't believe that spammer:
#1 video converter was the prog that I was using for a long time, really nice one, Paid - why should I pay some idiot support when they don't reply to me? - Anyway I decided to use some used keys so i use 'paid',
Fast #1 Video Converter, avi to mpeg, flv, mp4, 3gp, iPod, iPhone, psp, rm, mov, HD-DVD, DVB
If you haven't used #1, it is a nice prog tho, just go Video Edit Magic. It can do more than everything, more than the crap called Windows Movie Maker. It converts formats, resolution, uses even the windows codecs such as MSADPM, IMA ADPCM, etc.
Video Editing Software - Video Editor: Video Edit Magic
Forget about 'Any Video converter', 'Bla bla bla video converter' or any other crappy programs. Video Edit Magic is the prog you need, #1 video converter if you need to split and convert.
