How do I keep nxtvepg from changing the channel while Im watching TV?
This is a problem which should only occur with v4l2 drivers (2nd generation of the video4linux driver API), i.e. saa7134 and cx8800 – which only support v4l2 – or bttv version 9. Explanation: The reason is that v4l2 allows multiple opens on the /dev/video device, hence the old v4l1 trick of switching channels through the video device (which would only succeed if no TV app had already opened it) does not work anymore. The problem was already addressed early 2003 by designing a new driver interface which allows background data harvesting applications to lower their priority beneath that of interactive applications like TV watching. You can check if your kernel or video4linux module supports that feature by looking for ioctl VIDIOC_S_PRIORITY in videodev2.h. However it took quite a while until the new feature was merged into the main kernel line. Solution: Upgrade to nxtvepg 2.7.0 and linux kernel 2.6.2 (e.g. from kernel.org or check your distribution’s upgrade options). Experienced users
