KM - RC6-6 protocol same as RC6-6-32?

I'm a n00b to all this stuff, but so far I have successfully used two predefined keymap files to upgrade my URC-8910 with two new devices.

Now I was going to make my own keymap definition for the Netgear MP101 streaming media player. I learned a few keys and then looked in IR and the protocol it is calling out is RC6-6-32. When I select RC6-6 (the only comparable thing I can find) in KM, the functions tab is missing a lot of data that it seems should have to be there.

Here is an image of what I am seeing in IR after downloading the remote memory...

Do I just go along with what it says and enter that OBC into KM, or does this require KM to know about a new protocol?

Thanks

Here's some more info, in case this helps anyone.

I decided to try just doing it with the RC6-6 protocol. I learned a few keys like power and 1-8 to try it out. Strangely, the OBC as shown by IR for 1-8 were 1-8.

Then, I entered a device code of 128 as that's what IR was showing. Howeber, IR also shows a sub-device that seems to randomly alternate between 5414 and 5542 from key to key.

So after I entered in power and 1-8 in KM using just the RC6-6, device code 128, and OBC of 1-8 and 12 for power, and then mapped some keys and uploaded it -- all the keys worked.

I was happy and went on to do more keys. But after I added the next batch and uploaded, none of the keys worked anymore...even though all I did was add some new functions and paired them with new buttons.

I'm going to experiment now with dropping and adding functions and see if I can find this strange line at which it stops working.

Anyone got any ideas?

Well, now I can't get it back to its once-partially-working state.

I did more searching on RC6-6-32 here and at Yahoo. I saw that other people had similar questions/problems with this, mostly in relation to the Windows XP Media Center remote, which it sounded like used the same protocol. I wondered if maybe there was some way the media center upgrade file could be hacked into working...but I lack the understanding to try that...

I did notice that there was a sort of pattern in the media center keys. Power's OBC was 12 there, also, and the volume up/down matched, and the numbers, and some others. I tried upgrading with it just to see if any of the buttons would be picked up by the Netgear and no luck. Maybe someone here knows something that could be changed to make it work?

Now I realize I probably posted this in the wrong place -- sorry about that. However if anyone can help please respond or refer.

I think that you may need to modify a registry entry in the Windows XP here is a thread about it.

Modifying the registry entry is an inferior kludge required if you have some inferior remote such as a Pronto or an MX, etc.

You can generate the signals correctly with a JP1 upgrade.

Somewhere MR Cinema7 posted an upgrade for this, but I forget where.

I also created a protocol executor for this. I can't remember whether I posted it anywhere. It might not have been enough smaller than the earlier one to be worth confusing people.

It just alternates. It isn't random. RC6 has a "toggle bit" that's supposed to alternate. This implementation of RC6 toggles the wrong bit, but the upgrade for it takes that into account.

That's because of the toggle bit. The registry fix makes the PC ignore the fact that the learned signals don't toggle the bit. But it's better to switch the upgrade which does toggle (and leave the registry unchanged).

If you're talking about the Windows Media Center upgrade, it's in the Misc folder.
