opchiasm,
I found the sony command code for video 7 (and others if they aren't included with the Mx-700 070 codes) at the following link:
[Link: anycities.com]Then I made the conversion to the OFA EFC code at the following link:
[Link: anycities.com]and programmed my Radio Shack 15-1994 remote with the discrete video 7 code... which worked... so I learned it to my MX-700.
There is probably a more "direct" way to get to the OFA code, but I couldn't any listings for the apparently fairly new video7 code.
I also couldn't find this code in any of the CCF files, otherwise I probably would have converted it from there.
I don't know if this will provide any value, but I'll export and upload my KV-36HS510 device to RC shortly.
