After using knoppmyth for quite a while and having no problems besides serious interlacing artifacts, I woke up to find no tv on myth this morning. The only thing I did last night was change the time and reboot. Now, when issuing a dmesg |grep ivtv get nothing. However on boot, it shows it loading the ivtv driver but does not register the driver with the device like it used to. By the way, I'm using a pvr250. It also appears that it is loading the bttv driver despite having no other cards in the system.

Any ideas?
