Looks like a time date problem.

Have you try another skin and deactivate crossepg?
You can also delete the epg.dat in hdf-toolbox.

Test this with default skin in image and deactivate other epg plugins if you use them.
Also check that you start the box on a channel with correct date time sending.
Delete epg.dat in hdf-toolbox and restart the box to cleanup epg.
Switch between using time from transponder or from ntp time.

works on gigablue 800se plus?
