Well, I thought I'd try Sony so I sent them an email. Here was their response.

"Thank you for contacting Sony Support.

I'm sorry for the difficulty you're experiencing to program your Universal Remote Control to control your Sony Home Theater System. Unfortunately, Sony is unable to provide support for Remote Controls designed by other manufacturers. Manufacturers may assign different code numbers in their Universal Remote Controls to identify the Infrared (IR) signal of a Sony product. Thus, the code number used for operating a Sony product in one Remote Control may be different from that used by another. For information on programming your Universal Remote Control, please contact the manufacturer.

Thank you for your time.

The Sony Email Response Team"

I wasn't asking for support for my Universal Remote, I was asking for the Vol+ and Vol- hex codes for their unit. It would be nice to have real customer service.
