[mythtv-users] Nova-t 500 blank screen requiring reboot

[John Taylor]

Hi,

Running mythtv 0.20.20070821-1 on Ubuntu desktop kernel
2.6.20-16-generic with 1 Nova T 500 DVB dual tuner PCI card (non
diversity version model 289 SL-289-V2.1-UK). Also have an Epia M
diskless frontend running minimyth

Card was installed according to the wiki:
http://www.mythtv.org/wiki/index.php/Hauppauge_WinTV_Nova-T_500_PCI

on a fresh install of Ubuntu

My problem is that the system works absolutely fine on first boot, but
after a day or so, the tuner seems to drop out. I get a black screen
when watching live tv on all channels, the OSD telling me I've got a
signal strength of 49-51% and alternates between lock and partial
lock. Programs will not record when the system is in this state. The
problem fixes itself when the backend is rebooted

Is this a card, driver or signal problem?

Any help very gratefully received!
