Somebody correct me if I am wrong(and I could very well be), but isn't that 1/8" jack in the back for if the DVR were able to control other devices, as in, if you had a VCR in your setup, you would plug the cord into the back of the DVR and put the other end in front of the VCR's IR receiver.

I know this is what the jacks were used for before STBs were DVRs.

As an alternative idea, somebody suggested this:

a few weeks back on the board. I don't know if it worked, but it might be worth a shot.
