Well, it is always tricky to upgrade the kernel on our TV machine, and this time it was even trickier.
like always, had to modify /usr/src/linux/drivers/media/video/bt8xx/bttv-input.c and change the ir->mask_keycode from 0x1f8 to 0x8f8

case BTTV_BOARD_WINFAST2000:
ir_codes = RC_MAP_WINFAST;
ir->mask_keycode = 0x8f8;
break;


Failing to do this results in a remote that has a few duplicate keys, I don’t know why this was never patched upstream, but that’s life.

The second part involved testing with IRW, which surprisingly failed this time to detect a few important keys such as POWER, CH+, CH- and more. Turns out I had to update the lircd.conf manually this time, as a few event codes has changed. This was done with the help of a small program called evtest.c (compiling with gcc was really straight forward). Hitting the missing keys on the remote resulted in the event codes showing up which I had to replace in the file. (the right and left keys are switched for some reason between their description in the event and their real placement).

I really hope this information will help someone lose a bit less hair on this.
