DSS code misery

I've been wasting serious time trying to get distinct ON and OFF codes for the Sony DSS receivers. I've tried creating them for IR and SLINK. I've got 3 different Sony remotes that actually send a distinct ON command, but I've been unable to reproduce that code from the Slinke with my own program or with EZ Learn. Each of the three remotes produce the same sequence of 5 commands, but in a slightly different order.

Of the 5 commands produced, I can reproduce and transmit each one except the DSS Power On command. Somehow this command must use some additional type of encoding. If I replace the 0111010 (Power on) command with 1010100 (Power toggle) command (and the 11101101 suffix), it works every time. Unfortunately, I don't need toggle - I need ON!

The decoding from all 3 remotes is identical. I've made many changes to the sampling period, carrier frequency, timeout and minimum signal length, all to try and see if there is something else in the code that I'm missing.

I also own a HomeVision home controller unit. This unit also cannot learn the complete signal from the remotes.

Has anyone solved this problem? HELP!!!

Here's what the remotes produce:
