I bought the Sony RDR-HXD860S
first impressions were OK, looks like a nice piece of kit, not as sturdy as what hi-fi made it out but not to shabby at all.
Very easy to set up and use as well, the thing that let it down for me was in 3 areas.
DVD Playback - I was expecting it to match or better my 4 year old Pioneer 565a dvd player, it cost me £250 when I got it and it was very highly regarded at the time.
I used a Mark Grant HDMI cable to connect the sony player, and tried all 3 resolution settings, 1080i was by far the best of the 3 but you still had visable jaggies on things (i used CARS DVD to test) I even tried using the same scart cable as is being used for the Pioneer and that didnt help.
Freeview -
again really easy to use, same interface as with all sony freeview stuff, i used to have the little stand up sony freeview box and loved it. This however gave a really poor picture, very blocky and pixelated, no where near the quality of my internal freeview unit on my TV. I found it quite unwatchable, basically the normally excellent channels like bbc1 etc looked like the really carp ones,
Recording -
yet again, fantastic to use, but results not that great, HQ mode was clearly lower quality then the source, HQ+ did come very close of the original, and would be watchable if the source was better. does use allot more hard drive space though.
So all in all I wasnt very impressed, wasnt just me either, the missus was sat watching while i was doing all these comparrison tests and she could notice the differance in quality to. To be honest im just not impressed with any of these freeview recorders, I went out and picked up the highly rated one from rthe BIG food store, just a freeview tuner and 1 160gig HDD, no dvd etc, and again the freeview picture on that was rubbish.
In the end I am just going to go back to using my PC upstairs with a TV card (better quality then the sony DVD HDD) and using media centre I can record what I want, its not ideal as i have to make sure the pc upstairs is on and turn on the 360 but at least it gives me the results im after.
