Ive had this card working since it was supported in the cvs up until
about 4 weeks ago. Since then I am getting the following error when
loading the driver:

It should be noted that loading mt352 afterwards makes no difference.
Loading bttv card=123 makes no difference. I can actually produce the
same output using just modprobe dvb-bt8xx. Ie bttv seems to be
autoloaded as does bt878 and mt352. You get eh following devices loaded:
/dev/dvb/adapter0/demux0
dvr0
net0
The relevent loaded modules are:

I am using the 2.6.16 kernel. V4l and dvb are all compiled as modules. I
am also using Udev. Im really rather stuck here. Id say it looks like a
bug to me in either the mt352 or dvb-bt8xx driver. The problem has
cropped up before but theres no resolutions posted on the maillinglist
or else where that i could find.
Any ideas?
Neil
