DVI all-in-one HT system: what are the options?

[asherpat]

i have a top of the line (well at least it was, 1 yr ago) DLP projector (IF7200) and currently i feed it via component from a cheapie DVD player (the celebrated Maplin's brand - Tangent). The picture is very good (though sometime the Tangent "stutters") but i'm burning to know if DVI-D will be visibly better than component.

I also need a HT system and spkrs but i find it hard to find HT systems with DVI or HDMI output, except Samsung HTDS910HD (see digiuk.co.uk), and even this one is sold only by one vendor.

Anyone knows other all-in-one systems with DVI? Anyone has experience with this Samsung? Help!
