Ok so I just got off the phone with Toshiba HD-DVD customer support. Here is what I was able to get out of them which took some work because they wanted me to be in front of my unit and I am currently at work (don't tell my boss
First thing Sandy (nice lady) said to do was to unplug the unit for 2 min. Her explanation was that since these units are effectively compunters they need to be rebooted after an update. She claims this has helped a couple of customers she has delt with.
The second bit of info that I got from her was that they feel this is a disc issue. Apparently there is a VERY large number is complaints with Universal discs. She was also aware of complaints with the movie Transformers specificly. She was indicating that these are bad discs causing the issue.
The third tidbit I got from her was that I (we) should be powering on our displays before the HD DVD player. She wasn't sure why this was working (this is from customer feedback) but her thought on it was that because of all the communication that can and maybe does go on between equipment via HDMI that the player being on before the display is causing an issue. I would have written this off but there are people that report no issues and say they are hooked up via component cable (AV99GT above for instance). I may try unplugging my unit and hooking it up with component cables to see if that resolves the issue.
So maybe we need to have a different poll...who is getting the errors and not and then what method of hookup are you using?
