I have been searching for a potential solution for a while now, and I see there is a lot of knowledge in these forums, I am hoping someone can help me, or point me in the right direction.

I have an ExpressVu 3100 set top, and a Daytek P30 DVR. The 3100 can be setup to auto-tune channels and send out an IR signal to the remote which then controls the VCR.

The problem is the 3100 doesn't have a code for the DVR, and I tried alternate possible codes, but none seem to work.

I am hoping for a more universal solution.

Has anyone seen a remote, or IR-IR converter that can be learn the 3100 IR signals, and learn the DVR IR signals, and when the 3100 sends the control commands, this remote/converter will then send the DVR IR signals out?

I have seen there are certain IR blasters that can be attached on or near the IR ports on the equipment.. having them fixed would make it more stable, where having a remote would always have to be pointed at the equipment. If the remote fell in the couch, or the dog took it, then it wouldn't operate.

I have searched all over the web for IR-IR converters, transformers, send/recieve, programmable.. but no luck.

There is a terribly clumsy approach that might do this, but nobody has thought it necessary enough to make a product to do just what you want.

Xantech has a device that will receive a Xantech IR code, then spit out an RS232 code. And another one that will receive an RS232 code and spit out a learned IR code. The glitch here is (I think) that you have to start out with Xantech codes, so this might not work. And the hardware could run hundreds of dollars.

Thanks Ernie!

I like the idea of having some kind of a controller to broker the codes.. Following along the lines of your idea, I did some more searching and stumbled on something else that is along similar lines.. there is a USB UIRT that connects to a PC, this could both recv & transmit the codes for the Sat Set Top & DVR. I could use a software to link the events, something like Girder.

I am wondering if you or anyone has tried something like the PC software Girder connected with the USB-UIRT and linking the events from one set top to control another?

In my case, the Sat set top to send out the VCR IR codes, Girder recv's, triggers event that would then send out the associated DVR IR code.

I figure the total cost of the USB-UIRT & Girder software ~ 100USD + shipping. I have an old laptop that I can rig-up for the platform and hide away in the back!

Do you foresee any things I may have missed or potential pitfalls? Has anyone tried this before? (Sure beats buying a new Sat Set top or DVR, or both!)

Well I found the forms over at Girder and it seems that other people are doing this.. so now I just have to figure it all out .. looks like there are some big pitfalls.. but the posts are from 2002.. hopefully things have been sorted out! :)

I don't like the overcustom approaches and solutions that you have to get into when you cross platforms. Gawd, that sounded like NewSpeak! Let's try again - -

I wouldn't think of using a computer to control a DVR, especially if it were just something I had to stick into the middle of the process to make things work. I would stay in the world of remotes, and keep the computer stuff connected to the computer stuff.
