Although I have the BD-P1000 hooked up to a Panasonic 1080i LCD projector, the player failed to recognize the best possible video feed and defaulted to 720p. Neither the remote nor the player's face has a button to switch between resolutions, leaving the setup menu as the only option. Upon selecting 1080i, the following screen appears:

When finally completing the switch to 1080i, the menus substantially shrink in size and an annoying vertical flicker plagues all screen text:

The HD-A1 doesn't have this issue when switching to 1080i. Is it a failed handshake between the projector and player? The DVI to HDMI converter I'm using? Bug in the menus? I'm not sure, and I don't as-of-yet have a 1080p video device to test for the same issue. Flickering text in menus I can live with. Any flickering appearing during software playback is absolutely unacceptable.
