I have owned one of these for about 3 weeks now and in principal love it. My problem which is driving me absolutely nuts is recording from HDD to DVD. At best it can be described as erratic. The problems seem to be mainly when using high speed recording. The recording will usually start then at some point it will flash up "repair disc" then "couldn't repair disc" = coaster. (according to the manual this is meant to be due to a power loss which just doesn't happen) Also if it does manage to complete copy it won't finalise or if it does it can't read the disc it has made. In my frustration I have tried the following (all DVD- of course) - Datasafe 4x R & 8x R, Datawrite yellow 4 x R, Datasafe printable 8x R, Verbatim 6x RW, Mitsubishi 1-2X RW, Mitsubishi 4 x R, TDK scratchproof 2 x RW. At best I am getting a 50% success rate with High speed and some optimised are also failing. I am about to send it back but before I do can anyone tell me- 1) Has anyone had success with these media. 2) If not what media have you had success with? 3) Is High speed copying generally more unreliable? 4) Could the machine be faulty. I really want to keep it but can't afford to at this rate! Anybodies help would be greatly appreciated.
