Xvid/Divx files/how to change res to 480x272 to fit fullscreen on Archos 604 ?

[sunny]

Hi....

Can someone please help.

I have just bought an Archos 604 Multimedia player.

I have many Xvid and Divx files on my p.c (at various resolutions) and wish to put them onto the Archos.

But the resolution of the Archos screen is 480x272....when I put the files onto it from p.c, it cuts off some of the top and the bottom on the Archos screen?

I'm assuming it's because the res of the original files on the p.c is not 480x272,some are higher and some lower.

Question is ....What is the best software to use, to re-size the resolution of Xvid and Divx files to 480x272....?
So that I can view the files in full screen on the Archos.

Thanks for any info.
