All companies prefer to settle rather than see, even a "slam-dink" case that almost assures a win in court for them, continuing to pay those very, very, very expensive legal fees and not focusing on making money from their product or service. While they may not have been talks regarding rates, there was certainly communications regarding SETTLEMENT, and that's what this is about.
Yes, AMC wants to settle, too, but the problem is that Dish thinks AMC's settlement terms are too expensive of constraining. AMC would be pleased if they could get sufficient cash as restitution and new carriage rates at better rates to them with even guarantees that Dish carry any future AMC channels and provide them all in HD (and maybe even pay extra for the HD feed), and whatever else they can get to strengthen the access and numbers of AMC channels, so the company can look good for the long-term so they can get higher ad rates, show growth and increased revenue going forward, not a one-time cash infusion (in a few payment, no doubt) court victory. It's all about their business and Wall Street in the long run and enhancing AMC's brand and offering that translate into things they can really brag about and get richer with in the long run.
