WinX has the WinX HD Video Converter Deluxe for $0. Here's a brief description of what the converter does:
"WinX HD Video Converter Deluxe is multi-functional video converter software, which supports converting all SD (Standard Definition) videos and HD (High Definition) videos. With this program, you don't need to squeeze dozens of video converters into your hard drive which have limited functions separately.
It perfectly fulfills your needs in video conversion via 4 ways: convert videos to SD video formats (AVI, MP4, MPEG, WMV,etc), convert videos to HD video formats (HD AVI, HD MP4, HD MPEG, HD TS, etc), convert videos to fit portable devices (iPad, iPhone, iPod, PSP, PS3, Xbox, Blackberry, etc) and HD devices (Apple TV HD, PS3 HD, Xbox HD, Zune HD)."
WinX has the WinX HD Video Converter for Free. Normally this software costs $39.95, but for a limited time WinX is giving it away. The software offers 2 way conversion between a large number of HD and SD video sources. Great for downconverting HD files to play on a portable device.
