I'm afraid a North American/Region 1 DVD of the Tour won't happen.
This is, I'm told, due to the distributors, not anything else. Trust me, this is something that has been asked about and addressed many times before.
Your best bet is, perhaps, to buy the PAL DVD (online or whatever) and find the multi region coding inputs for your player (and most will have them), so you can watch the PAL DVD at home.
No promises, but, if I can help I will. Initially, send me a PM, with your player details and stuff, and we'll see whether this is feasible.
