I’ve had a need at various times to convert files from AVI to MPEG, WMV to MPG, MPG to MOV, and today, WMV to MPEG4. Format Factory’s Media Converter does this FOR FREE!
Today I needed to convert a WMV file to MPEG4 for iPhone. Besides all the formats listed above, it lets you convert from “All to Mobile Device.” I picked the iPhone as the device and the file converted perfectly.
I’ve been using Media Converter for years and I love it.
