The only way to upload to an 8811 is by JP1 cable. So why ask here rather than in the JP1 forum?
And why ask at all rather than just look at the files for Sony in the DVD upgrades for JP1:
[Link: hifi-remote.com]There are upgrades there for PS2 and the contents of those upgrades are very similar to the upgrades for Sony DVD, which are very similar to the built-in setup codes for Sony DVD. So I'm not sure you need an upgrade at all. Maybe you can just use a built-in setup code for Sony DVD. If you need an upgrade, you have a few to choose from.
I haven't kept track of the IR receiver details of various game/dvd systems. A few years ago they all came without the IR receiver. Even if you didn't want the remote (if you wanted to use a universal remote) you couldn't buy the IR receiver without the remote. Now some game/dvd systems include the IR receiver so you can use a universal remote without buying their remote. But I forget which game/dvd systems do that.
