No these didn't work. I have already tried all 512 combinations for both the TV and the DVD player but found out that at least with the standard codes there are no discrete codes.

However I have found a workaround discrete power on code for the TV by using the "p->p" button twice, this turns the TV on if it is off and when it is on it switches quickly from previous channel to the current, and so doesn't disturp the current channel. But unfortuneatly the DVD doesn't have discrete codes.

And if you are thinking I input all the 512 codes by hand and clicked "Test IR" button in Pronto Edit, then no I am not THAT nuts :) I used a combination of the kixtart scripting language and winmacro mouse recording program to automate the input and clicking.
