I just switched from DirecTV to CableVision...
Keep in mind I am a "home theatre - video snob"
(in our main media room we have a 73" Mits which shows many defects in a video source)
OK -- the PQ with directv was and is better no way around it!
BUT -- me and the wife do love using TiVo. And the PQ of the locals is same as directv. National channels do have more micro blocking effects with motion.
But number 2 -- I am saving almost $50 a month which is a good thing, I have all of the channels in HD I could want (TMC, E!, G4, Travel Channel, plus a few others that DirecTV doesn't have yet)
I would like it if CableVision could increase the bitrates a bit (no pun intended) which would get rid of most of the microblocking issues. This might occur once they reclaim some analog channels to digital -- which I'm not sure CableVision will or is planning.
I would like DirecTV to offer better hardware, less rainfade, and offer a better package price (IE less money LOL) and start turning on more national hd channels.
I have an install date with Dish - but I have pushed it out as I want to see how much I like Cablevision.
As of now (about 1 week in) we will stick with CableVision -- the PQ is good and is great on locals; can use TiVo DVR's which supports MRV (a big plus for us). Line up is also great. Not to mention no contracts - yup my price will go up after the 12 month promo but at that time I can ask for the reduced rate again and if they say no. I assume DirecTV or Dish will have all of the national HD channels lit up.
Sorry for the long post - I hope it helps
