[linux-dvb] Partially resolved HDTV5 lite and Twinhan DST
together + dst module question

Thanks for the response. Unfortunately that didn't fix it.
I tried both on the same line:
bttv card=0x71 i2c_hw=1 card=0x87 i2c_hw=0
That locked up!
Then I tried:
bttv card=0x71 i2c_hw=1
bttv card=0x87 i2c_hw=0
That didn't lock up, but the analog tuner still doesn't work right.
When I do channel up or down in kdetv, tvtime or xawtv, the indicator changes, but the channel doesn't actually change.
Just to be sure, I removed the DST card and analog worked fine again.
Note--sometimes when I start analog mode, I see a green screen. I am able to get a picture back by doing azap on an 8VSB channel! If I azap a QAM256 channel, the picture goes green again. I don't know if this has anything to do with my problem, but it's something to look at anyway.
I should mention that I am writing these lines in the kernel-2.6 file in /etc/modules.autoload.d.
It shouldn't matter, but just in case----

i2c_hw=1 causes bttv to use Hardware I2C instead of S/W based
Bitbanging. I think the HDTV5 uses S/W I2C

I think individually it can be called as card=0x68/0x71 i2c_hw=1
Maybe Greg could try that addition and try it like that and see how it
goes .. ?
ie modprobe bttv card=0x68/0x71 i2c_hw=1 card=0x87 i2c_hw=0
