Sky +?

I was wondering if its possible to convert videos i have on my pc to .TS files for use with my sky + box if so how would i do this?

would be ideal as i have a 160GB hdd and a lot of films id love to have on there!

Any sugestions on doing this?

Yea i suppose i could do but its nice to be able just to flick to my sky pluss planer and see my films i was just wondering if its actualy possibe i do have a divix player but dont really use it as much as sky.
