Can anyone convert tennis videos for my ipod touch. I try converting video on my school laptop and it wont let me since my school is dumb.
I can safely say I am an expert at that

Do you need a program that can convert it, I use
ffmpegX and
visual hub. Unfortunately those are only available for macs, but they are the best of the best and can convert to other formats as well.
A tool that works on pc's and macs is
MPEG Streamclip. It's also an editor, but if you export in MP4, you can select iTunes presets.
Also obviously if you don't have iTunes on your school's laptop, it's pointless. Furthermore, if I'm not mistaken, you can right click a video in iTunes and select "Create iPod version", but this method is slower and the quality is average.
Hope that helps. And if you are a Federer fan, I have a nice collection of Federer videos on my iTouch that I could upload somewhere.
