I guess that means you don't have the version of Universal browser that lets you directly paste in Pronto Hex.

But you do have Universal Browser (part of the MX-950 editor program) and it can drag Pronto Hex from a CCF file.

Most CCF files containing that Marantz signal have it in a form Universal Browser doesn't accept. But several have it in the form Universal Browser will accept. One of those is:

There seem to be a lot of different Marantz products that use that identical discrete On signal (I wonder what you do if you have multiple such products). The SR7400 receiver in the above CCF file uses the same discrete On as you quoted for your MV5100 VCR.

But maybe the page you got that info from is wrong. There is a pattern to the way most devices use IR signals and a VCR should not be using the discrete ON and OFF signals shown on that page.

I emailed a CCF file to you containing three other signals. The discrete On and Off for a Marantz VCR ought to be two of those three signals. I see no evidence in files I've downloaded from people who actually have Marantz equipment that these really are the correct signals. But logically they ought to be and they would be easy for you to test and find out.

Please report back on whether the SR7400 signals linked above work as discrete On and Off for your VCR and whether different the signals I emailed work.
