HOpefully you get it sorted! Better to try to keep it to all regions if you can, because then you can play English and Australian stuff (or American for that matter!). We bought an all regions one for that reason when we were in England cos the inlaws used to send us DVDs a fair bit.
Does anyone know what happens once you've used up all 4 trys on your computer? Only asking out of curiosity. Presumably someone somewhere can show you a cheat to fix that back up again if it lands on the wrong one?
And while I am on techy questions, what happens if we make a DVD on our computer - from own video footage etc. Would the DVD we produce be region 4, or would it be playable anywhere?
