I've bought the 970, loaded the modified firmware patch v.4A-0111, and am unable to up-convert beyond 480p over component on my rptv mitsubishi 65807.
Yes, the firmware seems recognized by the player. And also, I am pretty sure that I burned the 935.bin, not the backup. I used Nero at 48x. I could try the version burned at 8x with Burn at Once, but doubt that will help.
And yes, I stop the player when I press the HDMI button. It toggles 480i, 480p, then at 720p there is static/snow and no picture (expected with this no 720p TV). The problem is that when I toggle HDMI to 1081i, there is no picture.
At 1081i, the TV display goes zig-zaggy for a second or two, then blank (a blue screen like when there is no signal received). Is this what is meant by "losing sync?"
I've tried reverting to the original beta firmware hack (Version: MVer: 05.00.01.07 Batch: 1A-0613 from June 13, 2006)-- same results.
The DVD player is connected via one of my component cable inputs (there are two of them).
My TV definitely accepts 108i -- I've been using a DISH HDTV sat box for years.
All advice is welcome.
