I don't know if anyone has addressed this yet but in trying to set up a TSU 3000 for a Sony STR-V333ES receiver, I found that some of Wade Carpenter's excellent clean IR codes for it weren't accepted by PENG (BTW Thanks Wade for doing that work!). I had trouble setting the codes for the numeric keys and direct tuning.
It seems that PENG does inspection of the code as you enter it and there was a problem in the preamble where they were set to a burst pair count of 39 (0x27) where there were only 26 (0x1a pairs) (thanks also to Barry Gordon for the great intro on IR!
[Link: remotecentral.com]). In addition, the codes for numeric 4 and 5 were identical.
Anywho, I have an updated copy of Wade's spreadsheet with these changes and I want to share them so... if anyone wants them post back and I'll send them on -or- if those is charge of rc.com want to post this information, let me know and I'll send you the file.
