Yes - if you choose a program on your Digibox for autoview and switch of the Digibox, it will "wake up" the dmr 85 on the start of the program. IF you put the dmr 85 to EXT Link before of course.
I found out however, that autoview does not allow the Digibox to give out RGB. So make sure you put your DMR 85 AV2 input (where your Digibox signals hopefully come in) to "Video" instead of "RGB". Otherwise you might just record the sound without the picture.
I had this problem.
Also, my DMR 85 needs to be set on EXT Link 2 (check functions, setup, connections - mine is german so it might call itself slightliy different on yours). In the manual it says, that EXT 1 should be used, if the digibox can give out an impulse via scart, to start the dmr 85. My digibox actually has this function, but it doesn't work, when I put it on ext link1.
So ext link 2 is safer.
Good luck ...
