One long shot possibility is to email Hitachi customer support, tell them you want to use an advanced universal remote control and ask them if they have any technical information on the IR signals understood by their Camcorder. There is no reason to confuse them further by saying you need the info in a form usable by JP1. If they give you info in any meaningful form, the experts here can translate it. The main piece of information they have that we would need is something they probably call the "custom code". It might help if you ask them to include that in whatever information they can send you about their IR signals. Even if we had just the custom code, it should take only a moderate amount of experimentation to find the whole code set.

Odds are your email won't reach anyone who has a clue what you're talking about. But occasionally someone gets results by that method.

I can't think of anything else to try.

If any of the people likely to read your request here had the information you're requesting, they would have posted a JP1 upgrade for it before even seeing your request.

I glanced thru the DZ-MV750MA DZ-MV780MA pdf manual and it mentions that the remote control(DZ-RM4W) is only included with DZ-GX20MA and DZ-MV780MA models. It also mentions that it uses the VCR2 code set used by Hitachi VCRs and warns you to change the code set of the VCR to something other than VCR2 if you have a VCR nearby.

the owner I bought the the camcorder from sent me the complete inventory list included with it and it does include the remote control unit for it said the original one he had was broken on a trip he made and there is a remote sensor near the back of the camera for it as well
I couldn't find the owners pdf on the Hitachi website how could you have it I do have the owner manual and its a big book I also contacted Hitachi customer support and they never responded back yet and its been over two weeks

I looked at the manual from http://www.retrevo.com/samples/Hitachi-Camcorders-manuals.html and it mentioned that the infrared remote control sensor is at the front, right underneath the lens. Perhaps your model only has a line control and not the remote control? You should look thru the manual to verify your model has the infrared remote control sensor.

I just uploaded a .rmdu file for Hitachi's VCR2 code set:

http://www.hifi-remote.com/forums/dload.php?action=file&file_id=5215

Please test that and please report back your results, especially the meanings of any other OBC numbers you might find while looking for camcorder specific functions.

I tested it with CaptureIr and see that even though Play and Record seem to be the same signal in the functions list, they are sent differently. Record is sent with Device 97, subdevice 159 (just as it was in the CCF files I found).

I either forgot or never understood the operation of the Parm value 0x24. I think that must be what generates the special behavior of the record button. So for just one function per upgrade having the alternate device numbers, you don't need the helper upgrade I expected you to need. But if you needed functions with the alternate device numbers on buttons other than REC, you would need the helper upgrade.
