I have an Air2PC ATSC PCI card running a Fedora Core 3. Using the CVS drivers with kernel 2.6.11-5 segfaulted on the modprobe (i can post a trace if anyones interested), but on 2.6.10 it loaded ok aside from this i2c ack_error. dvbscan -cvvv works in a sense that it finds 4 programs from the PAT/PMT, and azap shows a signal lock, but cat /dev/dvb/adapter0/dvr0 > blah.ts does not produce any output. We also have a data pid on 0x2a here and I can not get data up from the dvb0_0 interface. If anyone could point me in the right direction it would be great.
