Can an external HD be used as my primary HD?

Can direct tv hd dvr be used in hd with 2 dishes instead of a new 5 LNB type dish?

• I bought a direct tv hd/dvr from Best Buy, due to the fact that direct tv could not have it installed for up to 6 weeks.(But they gave me the one year free hd use anyway) I currrently have it hook up to and old style round dish and it works. But I want the Hd and multi station recording. I also have a used dish network- dish that read sat 110 and sat 119. Can I use the dishnetwork dish for the 110,119 and then reposition the direct tv dish to get sat 101. Has this ever been done before?.. The set up screen for the hd/dvr ask you if you are using muliplal sat or just one, so I quess it able to due this if the signal for the dish network is the same? I don't ant to buy a dish or wait for d/tv to install. Thanks for you help

• Answer:

  I am unaware of any multiswitch that will allow you to combine the Dish Network dish and a DirecTV round dish. I also don't think the LNBs on the Dish Network dish will properly process the DirecTV signal. As of 2/2/07, only the DirecTV 110 satellite is transmitting HD signals. So, if you can find a trip sat dish, that would work for now. DirecTV is expanding HD and will be utilizing satellites in the 99 and 103 slots. When they are fully operational, you will the need the 5 LNB dish.
