I got my 910 from Krish on Thursday - it was one of only two they had left.
HDMI is definitely an improvement over RGB scart. I watched Titanic (admittedly a very well encoded disc) through HDMI and the results were pretty stunning.
I have a couple of gripes though.
1) As someone else said, navigation through the hard disk recordings is a bit clumsy, speeds 1 & 2 are quite slow but speed 3 is too fast so if I want to go forward say 5 minutes, I end up either taking ages, or over-shooting. Maybe I will get used to it.
2) As many have pointed out, chapters are not kept when recording from HDD to DVD-R.
3) I removed the advert breaks from an ITV recording on the HDD using A>B remove which worked well. However when I dubbed from HDD>DVD-R, the in-point of the various sections came about a half-second earlier than they did on the HDD. So although the edits looked perfect on the HDD with the ad-caps removed, on DVD-R playback, you see the last half-second or so of the captions! This is a real pain.
4) Is there any way to stop the on screen display (just a little box in the corner with the green "play arrow" appearing so often. It appears on layer changes on standard DVD playback, and it appears at all of the edit points in playback of my DVD-R recording from the HDD mentioned above - even though the machine is not able to recognize those as chapter points.
5) There seems to be no way to display the bit rate on screen.
If anyone knows more about how to deal with these problems I'd be interested.
Overall despite these issues and the bizarre DVD+R letterboxing problem, it's a great machine.
