Leadtek TV2000 - changing modes help

[genexis]

On a recent trip to Hong Kong I purchased a Leadtek TV2000 XP Deluxe. Without realising that it only supports PAL I and PAL D/K. Now the problem is that Australian TV i think is PAL B/G.

Well as it is, I am able to tune to the channels, ABC, 7, 9, 10 and SBS, but the sound is fux0red up. Only channel 10 seem to be Ok for some programmes.

So the question is, does anyone know of a way to hax0r the decoder or something to make it support PAL B/G instead or the current modes ?

The card looks exactly the same as the ones you can buy here in Australia. I've installed a few.

Thanks.
