I had slightly discounted DTV attached to my Verizon phone/DSL account while I waited 18 months for FIOS to reach my house. They partner anyplace FIOS isn't available but trust me DTV doesn't come close to FIOS' picture quality or reliability. As far as I know FIOS is still uncompressed.
Speaking of which I just hooked up my new FIOS 500GB DVR and it rocks. The old DVRs were limited to 160GB and were slow and unresponsive to the remote. The new box is much faster. Not as fast as I like but much better. If you have FIOS you have to get your name on the list and there is a one time $40 charge.
