I'm have Qwest DSL. They also used a 2wire modem, and not only did BTMM not owrk with it, but I had various other problems with it. I finally had a problem downloading HS iTunes content (only HD movies - SD movies and HD and SD TV shows worked fine) and the solution - which is detailed elsewhere on this forum - was to call Qwest and get a different modem (specifically, an Actiontec PK5000). BTMM works great as well and the other problems are gone.
Good luck.
