I need the unlocking code for toshiba dvd DR 410.

After getting clarification from Fixya I can pass the links below to you to check yourself

Some players are harder than others to do this but you may want to try here or here
Toshiba's and JVC's are the harder ones to do

I use a Phillips myself as it is not only cheaper but has much more going for it than many of the higher end units. i throw anything at it and it just plays

The older the unit that harder it is to do the region free thing with.
I let my EX have the panasonic (big grin)

If you cant find a fix then look at the codes available for cheaper brands and how easy it is to do it before you purchase one.

Just a thought.
