For my situation, these are the factors that keep me with DIRECTV rather than my local cable co., Time-Warner Cable:
1) I have waivers for CBS and FOX, which means I get the HD feeds out of NYC. TWC doesn't carry those nets in HD in my area.
2) I have Lifetime DVR service through DIRECTV.
3) I find DIRECTV to be more reasonable about adding additional DVRs than TWC and they have a more realistic capacity drives in their DVRs.
4) Other than HSI and VOD, I find DIRECTV to be more innovative and better seated to making agreements with major Sports entities, like the NFL Network.
5) The DIRECTV commercials are so much better than the TWC.
6) After 9 and 1/2 years with DIRECTV I'm just more comfortable with them and if I went back to TWC, I'd have adjust and I'd miss more of what I'd give up than appreciate what I might gain.
7) DIRECTV will be adding a lot more HD in a month from now. I don't really know what TWC will do.
Hope that's clear enough.
