JP1 files aren't really human readable. You need to install Remote Master, and open the file in that. Then download IR Scrutinizer. Use the protocol, device, subdevice and OBC from the functions tab to generate the pronto hex. It's probably going to match the ones you posted earlier since Sony codes haven't changed in years.

Here are the results:

EDIT: I just converted the original pronto hex you posted, and it does indeed match the codes above. So what you found in the JP1 file is the same as your original post. Any differences you see are just insignificant timing differences. The codes are identical.
