TV card losing channels

[eetaylog]

ive had my Nova-T500 for around a year now and have never had a problem. yesterday tho it decided to lose all the tv channels. after rescanning, it finds all of the channels again but cant retain them when i close mediaportal setup.
i thought it might be the onboard lithium battery on the mobo, but that is still at 3v.

im running MP 0.2.3.0 btw

please help!!

Your mediaportal.xml file could be corrupted, try renaming this to mediaportalold.xml, reconfigure mediaportal, and see if its corrected.

The tuned channels are stored by mediaportal, not your TVCard hardware.
