get the pchdtv-extra from pchdtv.com. it modifies modprobe.conf and adds
udev support.
When I set the capture card type as dvb it'll do a channel scan and find

dvb is for digital tv, while v4l is for analog tv. i believe hd-3000 in v4l
mode uses line-in for the audio. but in dvb mode, the audio should be
embeded in the stream.
and it seems a lot of people are having problem with hd-3000 since the dvb
driver was included in the kernel. it used to work fine for me when i had
to compile the dvb driver for the 2.6.11 FC3 kernel.
Any pointers or help would be greatly appreciated.
