Let's not over-complicate the simple concept, while over-simplifying the complex concept.
Let's not simplify the fact that echostar has indeed sufficiently advanced DVR technology over the years while TiVo has stagnated. Whether you want to label the vip622 a 'workaround' or the 922 a breakthru, nothing changes the fact that if you continue to build on an existing technology, you inevitably create new technology. That is that E* is doing, and aside from the obvious financial reasons, that is also why delaying these courtroom antics ad nauseum will continue to work in E*s favor.
And likewise, let's not overcomplicate the simple fact that it only takes one simple question to effect an outcome here. And that question was asked...so like I said, we are looking at a whole new ballgame here and the rules keep changing.
Just think, with the validity of the patent being subject to question, that would mean that any ruling on these issues, past, present, or future, are now all based on nothing more than a glorified 'maybe' until that nonsense gets resolved.
TiVo has not stagnated. Check the TiVo sites to see the new features they have developed.
