I'm in the same shoe that I need to play R1 DVD (tv series mostly).
I was previously using the x700 and the main issue is the incapability for source-direct resolution. It outputs DVD at 480p, and then the TV does the rest, which is quite disastrous.
Oppo is still the best IMO for source direct resolution.
Recently got the X1100 and though it does not do source direct, after trying for sometime, I'm now using it for DVD playback also. It's upscaling is way better than the x700, and the end result is a close second behind the Oppo. Bonus is you can use the same remote for your tv and player.
If you can find an Oppo, I'd still recommend that, else the X1100 is a close second.
