Corrupted OTA TV Recording

This problem started some days ago also with some problems with the sound
after sleep. The system records the OTA TV shows but when trying to playback
i get an error 'Can not find the required Video Files to play video, try
restarting Media Center or Computer'. (So annoying)

If I exit media center and go to where the files are stored (TV Recording
folder), and I double click the file from there, then it will be played in MC
as it should.

I have a custom made computer and this was working fine until some nights
ago (automatic updates??? they are set to be installed @ 3.00 am).

ASUS M2NPV-VM
AMD Athlon X2 4200+
2GB Ram
NVIDIA GTX8500 512MB VRAM
IDE 300GB OS HD
SATA 500GB TV HD
Hauppauge PVR150 MCE edition
Avermedia AverTVHD MCE180
Avermedia AverTVHD m780 MCE

All drivers up to date... As a reminder... it was working like a charm a few
nights ago...
