There is a thread on here somewhere that talks about this. You can use an old PS2 DVD Remote that came with the Dongle (the new ones don't because the new PS2's have the IR eye built in).
People have gotten the basic commands to work for the blu-ray, but I don't think it is a perfect fix, but at least you can play movies. I don't think you can use the other functions like the angle options and such.
I am in the same boat with the 880. I know you can pick the old remotes up at EB Games and Gamestop for like $5, I just haven't been able to find one yet.
