Just so I understand,
If I use the link provided for the 1.6 it will make my a2 region free? Then use the link for the e1 2.7and I would be good to go for pal.
Or is there a step in between I am missing?
Can't you download the 2.7 firmware from toshiba then burn it to a cd? Nero works for me for burning?
Alternatively have you tried a reset (while on - hold power button on unit for 10-15 sec) or reinitialize from the menu?
HD DVD player - connect HDMI to TV for video, HD DVD player optical out to Yamaha. This will give you surround sound, I have the HD2 and my yahama recognizes the sound as DTS - not sure what the A35 will down convert the sound to.
