I find some of the commercials can be a little annoying, but if that's what it takes for me to see the Tour over here then so be it. I am out of the house before the Live coverage is on in the morning so I record it on the Tivo and watch it when I get home with the commericals quickly skipped by. Thus making them much more tolerable.
I also have been editting them and recording them to DVD without the commericals at all so that I can get my fix during the winter.
