Hi Detrie,

I checkout out your system specs and you list your HTPC-TV connection as "PVR -> PC=Composite. PC->TV=HDMI". With the HDPVR1212 there should be no route to the PC via "Composite", it should be USB. Is this a mistake in your specs? Here is the connections I have (the dots are just there for spacing ;-):

STB (Directv HR-21) ---[composite/RCA audio]>>> HDPVR1212 ---[USB]>>> HTPC ---[SVGA]>>> TV
...........................................................................+--[stereo lineout]>>> speakers

I have my Directv H-21 on my LAN. Directv has an IP protocol to change channels (among other things) and so I use the Directv SHEF IP protocol to change channels from MediaPortal. There is a Directv SHEF plugin for MediaPortal that makes the connection between MP and the STB (search if it's applicable for you).

With all this setup I only need to control MediaPortal from my Harmony remote and I can control all my devices without any IR blasting. The Harmony remote turns on/off my HTPC and TV. Note: I have to leave the HDPVR on all the time (24/7) because there is no way to remotely control power to it. The HDPVRs IR capability is for blasting only (IR comes in the front and blasts out the port in the back - useless for me, so I just ignore it).

To control my HTPC via an IR remote, my Harmony 700 has to be able to send commands to my HTPC IR receiver. In my HTPC case (by Moneual) there is an inbuilt IR receiver for which there is also some supplied driver software (MX.Play). I had to program my Harmony 700 remote to be able to send IR commands that are capable of being read by the Moneual IR receiver. Luckily the Logitech Harmony database has the command set so I just mapped the Moneual IR commands to to my Harmony buttons (I have a spreadsheet to keep up with the mapping). Once the mapping is done I could send button presses from the remote to the Moneual and through to the Moneual supplied driver/software. This software lets me map PC commands to fire when an IR command is received. In my case I chose (after looking at several alternatives) to interface to MP via Windows Messages, WM_APP, (to which MP listens). I wrote my own program to send windows messages; it's called SendMessage and it simply accepts command line parameters (the message to send to what application) and sends the message (I'll post it here upon request if it's useful to anyone); I think I got the WM_APP Lparam list from an IRSS remote map file. The WM_APP message is received by the MediaPortal message plugin. Use this plugin to map the WM_APP commands to MediaPortal actions. Done ;-)

It sounds like a lot, and perhaps it is, but it works very well -- it' very fast (responsive) from the button press to the MP change.

So, if you have an MCE compatible IR receiver then you should be able to use the MediaPortal Configuration tool, Remote section - click directly on "Remote" in the tree and the first tab is an MCE remote. Click the "Use MCE remote" checkbox and configure command mapping.

Let me know if you have any other questions...
Good Luck!
