So you have a laptop and a PMP that won't play the same video formats - or you have a file that is flummoxing every device you own.

Mux says it has an easy solution in its online video converting tool, the "happy hungry videobot".

This basically lets you convert videos between formats.

All you have to do is upload your file - which includes WMV, MOV and AVI file formats - and it will then convert it for you.

You can choose from formats for the iPhone and iPod, the Windows Media player, Divx, MP4, Quicktime, Flash, PSP, Ogg, 3GGP and more.

The Videobot also allows you to enter the url of a flash movie from websites including YouTube, which it will then download for you.

In addition, Mux can be used to send video to video enabled phones, including the iPhone.
