I know this is an old post, but we have had Prism for the past 6 months and all I can say is that it is decent, definitely cheaper than what I was paying for Directv, but you get what you pay for. We have 4 TVs and only two of the 4 can view HD content at the same time, the other two sets have to be in SD. This also applies to the DVR. You can watch 1 HD show and record another HD, but if you have more than two HD streams running, then any other recordings will be in SD. This is due to the bandwidth limitation of the dual ADSL pipeline they use to deliver the service over. The HD quality is pretty good, but not as good as Directv. We have also had intermittent audio issue with digital audio, the sound will drop out occasionally and come back and drop out, its annoying to say the least, so we run most shows in stereo audio and not digital audio to eliminate the problem until they get it resolved. Overall its an ok service, we have combined internet phone and TV and the total bill is about $60 cheaper than we were paying for Directv alone. So overall it was about $150 savings when we combined everything.
