[Hampshire] Ubuntu 9.10, dvb and dual boot

Is anyone out there using a digital TV card on Ubuntu 9.10 and also dual
booting with windows? If so do you find that after switching back from
Windows to Ubuntu the TV card doesn't work, and you have to reboot again
into Ubuntu?
If not, can anyone tell me how I'd go about finding out what's changed
between 9.04 and 9.10 in terms of dvb firmware, drivers and dvbstream
between the two version of Ubuntu, so that I could try and figure out
what's broken.

Thanks,
Leo
