I have tried PIDs using valid keys without 4th and 8th pair of digit, and only once "00", without "01", and works well, with only the keys in this way, like this:
An example with fake keys as they are used:
F 03EB1FFF 00 1122334455667788
F 03EB1FFF 01 1122334455667788
This way works too:
F 03EB1FFF 00 112233556677
Without 4th and 8th pair of digits.
The decoder shows all the keys as seen above, all the keys like this:
CW: 0x1FFF 00 1122334455667788
CW: 0x1FFF 01 1122334455667788
Using the same PID several times with different keys, the decoder only accept the last one, does not try the other keys with the same PID.
I wonder if with DVB-S cards for PC is possible to try many keys with the same PID, as if were brute force technique.
The very large lists, as the last one posted in last page of the mentioned thread, can be managed with "EmEditor", and allows you to divide the list into several smaller files.
