I got L6.13 today as well, and confirmed it did NOT fix my 1080p issue previously posted in this thread for my Panasonic PT-AE1000U projector which supports 1080p24 just fine on HD-DVD.
My screen still goes on and off, and the projector's menu alternates between nothing and 1080p24 (I occasionally get the 1080p24 picture on the screen). I connected the projector directly to the 622 via HDMI (although I get no sound this way). I then tried a 30 second power cord reset on the 622 with the projector on the whole time, and it still failed. I then also tried powering off the projector and removing its power cord, doing the power cord reset on the 622, waited 10 minutes, then powered the projector back on. Same results again.
