No, pretty much once you sign the contract, you're in for the full 2 years with a $480 early termination fee. Some retailers offer cancellation periods, but they're unusual and must be done through the retailer you bought the system from, not directv.
Just to clarify a couple of things because I didnt read all 8 pages of 'sez you!' and 'oh yeah?!?'. Did directv install the multiroom viewing option in your house? If so, the plain receivers should be able to view content from the dvr's. With the media sharing option thats included with the dvr's, you should be able to show pictures on the tv from a pc. Video and sometimes music are a bit more problematic.
What dvr's and receivers did you get?
