Just got the upgraded channel guide and have a funky issue with it.
42' LG with a 7100-1 STB shows 2 1/2 hours of programming (guide wraps from side to side of the screen)
79' Mitsubishi with a 6200-2 STB only shows 90 minutes (guide has black bars on both sides).
Both TV's are set to 1080i 16:9
The different formats were in place day 1 of the upgrade.
