DWIEN,

I did try to get the T2 to learn a single command. That command being the "MUTE" button....still did not work (as the manual recommends, I used fresh batteries on both sides). More concerning to me was that the IR frequency of the learned sony command was 461.7, above the maxium 460 the T2 is capable of transmitting.

Also when examining the actually "waveform" of any STRDA90ESG command (latest library version), at the bottom left edge of the waveform is "UNKNOWN". Can someone who has this particular receiver working with the T2, examine their "waveform" for any STRDA90ESG command and verify the "UNKNOWN" is the expect description for these commands on the waveform review screen?

Any help is greatly appreciated.
