[linux-dvb] Pinnacle PCTV (Dazzle) 300i maybe i2c problems with newer code?

Hi,

I've just got a Pinnacle 300i, and I'm having some trouble with it....

I first tried 2.6.14.1, and then the nightly snapshot from yesterday.  
Tuning failed.

Having read the recent posting to this list, I've tried the 2.6.12 
kernel - this sort of works for a while - viewing with mplayer, output 
works OK for < 10 seconds, then output stutters, and stops.  Playing 
audio only streams, the   I tried building the 20050627 snapshot against 
this kernel - with this kernel I get output with a lot of corruption 
(random blocky garbage all over the image), and very chopped up, high 
pitch audio.  When trying to play audio-only streams, mplayer hangs up.

Unfortunately, I don't have a PC running Windows XP to check performance 
of the hardware under Windows (software is XP only, the driver seems to 
install under 2000, but the application won't - if there are any 
applications that I can install under 2000 to try and verify operation 
under XP, I'd be glad to hear about them).

I'm guessing from the messages below (companycode=0000) that i2c I/O is 
not reliable on this card with the newer code, any tips as to where to 
start looking would be greatfully recieved?  Is the fact that one is 
reporting "tuner 5-0060", and the other is "tuner 6-0060" significant?  
Is it reading the wrong i2c bus, or something?

Cheers,

Tim.
