     525      450      525      450      525    23625

That decodes as:
1100 0010 1010 0100

In the NEC protocol the second word is supposed to be the inverse of
the first word and it isn't. The timing is too short for NEC protocol
too.

Valid NEC...
1100 0011 1010 0101

Maybe JVC protocol but it is longer than normal.

The JVC decoder was unable to get started decoding it.  I don't think
the JVC decoder has been tested much. Take a look at it and see why it
couldn't get out of state 0.
