They don't work because they don't have a diversity tuner. J A M E S on bimmerboard has tried 2 or 3 units and as soon as you gain a little speed they crash. Euro hybrid video modules have a Microtune diversity tuner which works for the European DVB-T system but not in the US. Mobile TV is a little different than just playing a DVD disk it seems. I am unhappy because I just lost my TV.
