Tv to Monitor

Hey guys,

How we all doing?

I have a 44" rear projection TV that is not being used anymore, so i thought id hook it up to my pc just to be awesome =).

Anyways, i have the resolution and frequency sorted out (1920x1080 at 30herts), my problem, however, is that i cannot play any movies on WMP on that screen. On my default LCD screen they work fine.. But on the tv i get an audio error???

Makes no sense to me.

I was trying to read up on it, but i cannot find any info anywhere.

I'm a bit of a newb when it comes to dual monitors (unless its another LCD one hehe).

If anyone has any ideas, i'd really appreciate it!

Thanks heaps =)
