You still don't give us a clue why you need these codes. Is it because you want to use them in conjunction with a device you've already created for your sony receiver or add a new device all together?

The right way to go about this is to:

1. create a device called ZONE1 (or AMP or AVR or whatever you like)
2. click Save
3. Single click ZONE1 in the device tree on the left
4. Open the IR DB and ensure it's for ZONE1 and AUDIO for the IR data
5. Choose Sony under brand
6. Choose STR-DA5200ES (MAIN) under the model
7. Click Save, then Apply, then Close
8. You now have a device created with IR DB commands for ZONE1
9. On page 4 of that device are discrete power commands.
10. Load to your remote and test, if they work you can now use this device to
relate to your macros, punch-throughs, etc. Most that use these remotes for activity based use, will put this device on MAIN page 2 and hide that page and only use the device via references in the macros, punch-throughs, etc.

The software wasn't really intended for consumers. Seasoned installers in this biz can build these remotes out over breakfast for most systems, more complicated...have another cup of coffee :-) Your 950 that you ordered has the same programming scheme with added features of press and hold macros and variables, color and simple graphics changes...that and it loads much quicker. Best of luck.
