I have a HD-A3 with this problem.
Ordered a A2 from Best Buy for Business in early Nov, just got it a few days ago. Forgot I needed another HDMI cable
, so I had to order one from monoprice.
Hooked it up yesterday, stuck in 300, and started to watch it. During the intro, less than 2 minutes into it, it freezes with this error.
Cycled power, and tried again. Watched part of it, but about an hour in, it happened again.
Just called Toshiba, and they are going to mail me a new software version (1.3). Hope that fixes it, otherwise I have to see how to return this guy.
BTW, when it was working, it looks and sounds very good, running it into a Onkyo 705 and then a Sony XBR2 52" LCD.
