I am considering bringing up a class action suit against Comcast
First off, you better have a REALLY expensive lawyer and a lot of money. Comcast is a GIANT.
For any of us who have bought modern flat panel digital TV sets the change makes it impossible to receive the digital channels directly.
This is where you are confused. You couldn't receive digital channels directly before, you needed a converter box. This conversion by comcast only changes the way you get their analog channels.
Instead we are forced to watch totally unacceptable quality on horrible antique RF interface
Actually, the RF interface is very much capable of transferring digital signals. But with that aside, I don't see how you are complaining. Before this transition, you hooked up an RF cable from the wall to your tv to get the analog cable channels. Now, you hook up the cable to the box, then to the tv. So you are STILL using RF, just like you were before.
Furthermore, I mentioned that the statement on Comcast web site, in its FAQ section is pure case of misrepresentation. In response to question #8 the company states:
A digital adapter (also known as a DTA), simply provides digital-quality signals.
As we know, that box, with its antiquated analog RF output, is not capable of doing this.
I don't know what else you want. If you get a box with a standard a/v (red, white, yellow) output, you will still be using analog. The only way to get a purely digital signal to your tv is to use component or hdmi, which you would need to pay to rent an HD box to get that.
I was further told that I was the only person calling them regarding this issue
Maybe because you don't know what you are talking about.
