Mac-  Sorry for sending this twice, I just noticed this never made it to 
the linux-dvb list, so I am resending.

Finding the reset line wasn't so bad.... Now I have the frontend loaded, 
and I can get a lock, but no ts yet.  I can't scan for channels either.  
This is (very short) atscscan output:

Take a look at dmesg, for some reason, when I have bttv compiled with 
dvb enabled for this card, the tda9887 chip doesn't always get 
autodetected.  However, when I don't set .has_dvb =1 (bttv-cards.c, line 
~2410), tda9887 always shows up:

DVB: registering frontend 0 (LG Electronics LGDT3303 VSB/QAM Frontend)...

...and that last line makes me wonder how come cx88-dvb wasn't designed 
to behave the same way.  cx88-dvb prints card name instead of frontend 
name.

Anyhow, below is the current patch... I don't feel good about the 
.serial_mpeg setting in the lgdt330x_config struct.  I don't know if 
that's supposed to stay there or not... I figure it should be chomped, 
since there is no mpeg chip on board, but it looks like lgdt330x is 
expecting something to be in there.  I have tried both 0x40 and 0x00, 
neither made a difference.  What do u think?
