Thanks for this. Between MakeHex, iRscrutinizer, the existing codes on remotecentral, and the manual Mark provided, I sent a support request in to Harmony with what I think will work. Will update here when I hear back. I went with Protocol Sony20, Device Code 26, Subdevice Code 39, Function 72. (72 being the conversion of 48hex to decimal)The VPL-VW1000ES Protocol Manual has instructions and codes for all functions. I'm sure they're all still supported. On page 13, it has all the aspect discrete codes. (I tried to attach the manual here, not sure if it worked but here is a link: http://hifiandtheater.com/files/VPL-VW1000ES,VW1100ES_ProtocolManual.pdf).
You would take these codes and run them through MakeHex (here is a binary built: http://hifiandtheater.com/files/makehex.zip) to generate pronto codes.
Once you have the pronto codes, they can be output by usbuirt or learned by harmony etc.
