Hi, It might be the dvd burners not being compatable with your pc and windows but this is unlikely.

Try updating the bios but if you dont have a floppy then i dont know if this is possible.

Reinstalling windows might work.. i have heard there is a way to reinstall windows media center without formatting the computer hdd (hard disk)

erm.. it could finally be the wrong drivers or out-dated drivers. try searching on google for them.

oh and Welcome To itsallpc!
