This is a new box with latest updates.
Looks like bug in the firmware. :(
At times, the video on the Guide window works great, but when I change it to full-screen, the video starts SCROLLING horizontally.
Current work-around:
REBOOT MAG256W1 : and bam, it works. :
But again. this happens too often when I switch on the TV for the first time.
I'm sure there is bug in firmware and needs a fix. :?:
