The codes as posted are correct for Panasonic DVD's. They are also the same as the codes posted in the Panasonic discrete codes section for DVD's with the exception that there is a slight error (although it will probably work) in the first Power On code at remote central.

These are all Panasonic protocol device 176. On is 62, Off is 63. So there is actually two "words" that are different in the Pronto hex. There is a lead-in 48 bits of data and a lead out. The first 8-bits are always decimal 2, the second 8-bits always decimal 32, the third 8-bits are the device code (decimal 176 for DVD's), fourth-eight bits are sub-device (0) and the fifth eight-bits are command (62=On, 63=Off) and the final eight bits are an XOR of Device, Sub-device and Command.

IMHO the issue here is not whether the commands are correct. Rather that the way certain models work may vary and therefore the one in question apparently does not respond to the discrete commands in a useful way.
