I am getting 2 HD DVRs from Comcast and they will both be in the same room. I know that Tivo and DTV dvrs allow you to change one of the IR codes so that you won't have the problem of both DVRs being controlled with the same default code. Just want to find out if it is possible to manually change the IR remote codes on the Comcast DVRs from Motorola. I don't know what model I will be getting but suspect the 34xx or the 64xx for sure.

Another question, are these models able to have an external HD hooked to the back via Esata? If so, do you just need to power cycle them with the external drive hooked up?

Thanks in advance!
