Unfortunately, MythTV seems to open the device for tuning, closes it, then re-opens it for recording. This sequence causes the Hauppauge HVR 850 (and likely others) to loose its tune, and we record a white screen. If I keep a user on the device by running 'sleep 365d < /dev/v4l/HVR850/video' in another window, I am able to capture video. (No sound, but that is a separate issue I've not looked into yet.) It is arguable that V4L should restore the previous tuner settings when waking it up, but handling this in MythTV should also marginally improve channel switching speeds.",Bug Report - General,closed,minor,unknown,MythTV - Recording,0.25,medium,Invalid,,,0
