Hi there. I have the Z2 (for over 2 years now! And still on first bulb too!!!).
1.the dvd player make and model:
Samsung HD745.
2.what connection you are using (and the length of cable) eg; component/dvi/.:
DVI cable that came with the player, about 1m.
3.what set up you are using on the player (if applicable) eg; upscaling etc..
I use 720p upscaling on DVD's and DIVX files.
4.or any other factors which may increase pq?:
Switch between Pal and NTSC depending on DVD you're watching.
5.give the pq a score out of 10 (be honest!)
This totally depends on the disc you are using, but as an average I'd say 7.5, some movies are up there in a 9. (I'm saving the 10 for when I get to watch some true HD on it as my faithful old laptop hasn't got the oomph to play any
I've been really pleased with this player. It has allowed me to not only feed the Z2 with it's native resolution, but has given me a great picture, allowed me to play Divx files, and also let me experience SACD too. I know you can get the HD950 for about £120 from Richer Sounds, and this has HDMI rather than DVI. I believe it comes with a DVI-HDMI cable in the box too. (Please someone correct me if I'm wrong). This is the latest version of the player and also comes in black, if that's any use to you.
As a final note, if you haven't got any screen sorted out, I use one of the 6foot (ish) blinds from Ikea that only cost about £20, and it is great value.
Cheers,
Dean.
