Dual Layer DVD Discs?

I'm thinking of getting a few of those dual layer DVD discs for when I'm burning movies, usually I have too compress them too fit on my normal -/+ Discs and I'd rather have some of my movies the highest quality possible.

So just two questions:

Am I doing anything wrong when burning?
I've burned a few episodes of TV shows (which wern't high quality too start with) onto +/-DVD discs and never noticed any quality loss, but since I've started burning high quality movies... I've had too compress them, too fit on a standard DVD disc.

So, that happens for everybody, right? or am I doing something wrong??

So, do I need a certain DVD drive too burn dual layer discs?
The one I have in my computer definately burns all +/- DVD discs I've tryed, and also I think those DVD Rom discs, not sure though.

So basically can my normal drive which burns +/- DVD discs burn dual layer +/- DVD discs??

Hopefully someone knows what im on about.
I kinda need them soooon, any advice is appreciated

Thanks.

You'll need a dual layer burner if you're isn't.

1) Um, yeah. Don't really understand, but yeah if the original file won't fit onto the disc it'll have to be compressed.

2) What model is your drive?

Yeah, err nvm the first question.

How do I find out the model of my drive? Can I find it out on my computer somewhere?
Like here; start>programmes>accessories>system tools>system info? If so, where do I go from there? lol.

Thanks man.

All my faith crushed in a single sentence.

It'll be worth the money in the long run. How much do they go for?

So basically, I'm screwed?

SWEET!
