Hauppauge HD PVR and Linux

Last week I've tried to run Hauppauge HD PVR under Linux (Ubuntu 12.04), after successful run under Windows 7.
After reading and trying things from, I've still found that command of reading stream from device is executed with error:
cat /dev/video1 > test.ts
cat: /dev/video1: Input/output error

Later I found that if there are no video cables (with some signal of course) connected to HD PVR, this error is occures, unlike Windows if no cable is connected we have blue screen as output signal.

After connection of component (YPbPr) video cable, you need to configure default video input of your HD PVR device. You can do it with next commands:
rmmod hdpvr
modprobe hdpvr hdpvr_debug=1 default_video_input=0

Default video input values for HD PVR
0=Component (YPbPr)

Or using v4l2-ctl tool (from v4l2-utils package).
sudo v4l2-ctl -d /dev/video1 --set-input=0

After that, I've successfully captured video stream from HD PVR.
