I have an Alienware M14 X with an Intel i7-2630QM and Series 6 chipset. I've updated the WiDi drivers to 2.1.42 and the HD Graphics drivers to 184.108.40.206.2361, but I still can't play DVDs on the TV. I've tried to read all of the information on this site and I think I've done everything I'm supposed to. Oh, and I am using the Netgear PTV 2000. Is there something else I'm missing? Please help!
