Patch commit message was totally missing and I did a *lot* of reverse-engineering in order to understand patch (actually all these patches). What I discovered, not sure if correct, but that patch updates IT9135 BX chipset tuner related inittabs. Tuner config 60 and 61 was updated. I take latest IT9135 windows driver binary from Hauppauge and extracted inittab for tuner 60. It was just same as here. So I suspect these tabs are just same than latest windows. Firmware is likely same too, but I was too lazy to dump it out from windows driver and compare... Also, what I suspect, the 0xfba8 register write I removed from that patch, is some clock output provided by demod core. That is clock source for tuner, right? regards Antti -- http://palosaari.fi/
