Are there any compatibility issues with the Sony Blu-Ray STB and U-Verse? I had a Revue, and U-Verse over a year ago, and switched to TimeWarner cable partly because the U-Verse box would constantly reboot when used with the Revue. I finnaly got rid of the Revue due to a host of hardware problems, and bought the Sony unit. Now AT&T is offering a $300 gift card to switch back, and I'm thinking about it, but I'm afraid of the old reboot issue. Anything to worry about with the Sony and U-Verse?
