Hmm, then only thing left is, use MPTestTool & test to view a channel & then attach the logs back here, that will tell us if it's MP Player or TV server thats not working correct.
Hi,
Seems like problem it's with TVE3, if you have setup the cards as hybrid try to undo that & disable EPG grabbing(tab General -> EPG & disable) for now & run preview from TV Server management console.
