zapakh writes "A federal appeals court this week upheld a lower court decision that accused DISH Network and EchoStar of continuing to infringe on TiVo patents.' This is a follow-on to a Slashdot story from October. Despite a 'Herculean effort' by EchoStar in redesigning its DVR software, the ruling agrees with the district court that that was not a major redesign of the software. The patent in question is titled 'Multimedia time warping system.' TiVo is pleased with the ruling."
