The only DVRs that didn't do that was the 501 era.... over 15 years ago. I will be REALLY surprised to see that fixed.
Well, my memory is different. True 50X, 510 era, but also, I would add, the next gen DishPlayer 52X and 6XX DVR's, that did NOT behave in the frustrating way that has been described. However, IIRC, it was the ViP's that first exhibited the frustrating jump to Live after a Skip Back. It was BEFORE the ViP's availability that TiVo filed its infamous lawsuit against Echostar for infringing upon TiVo's "Time Warp" patents (that would be another name for "Trick Play").
It has been suggested on this forum that the ViP's were designed so they would have no way of violating TiVo's patents named in the lawsuit (some on this forum had stated that Echostar moved to using HARDWARE instead of software to achieve "Trick Play"). While all of Echostar's (specifically Dish's in-house) DVR's after the Original DishPlayer with software by Microsoft, but before the ViP's were named in the TiVo lawsuit. The ViPs' were, therefore, considered "non-offending" DVR's because they were never subsequently named in the original TiVo lawsuit. In fact, it came out in a Quarterly Conference Call that, consistent with reports in the Press, that Dish had been warehousing extreme numbers of ViP DVR's for the
implicit purpose of using as change-out DVR's to replace the older DishPlayer models 501, 5XX (single and dual tuner DVR's), and 6XX DVR's if Dish ultimately had to compensate TiVo as per the claims in the lawsuit.
FWIW, eventually, Dish put in place a "work around" for all the "offending" DVR's, but did not tell the "rouge" trail Court in Marshall, Texas. The Judge was angry, but wrong in, essentially, discounting the "work-around" because an Appeals Court admonished the Marshall, Texas Court for other transgressions during the trial and further ruled in favor of Dish regarding the "work-around" that would, essentially, require a whole NEW trial. Then TiVo CEO Tom Rogers accepted a far LESS lucrative settlement with Echostar saying he didn't " . . .
want to wait for the Supreme Court." It was a very cheap settlement for Echostar that got them ALL of TiVo tech at that time, and Dish dropped its suit against TiVo and allowed TiVo a few of Echostar's patents. But TiVo was still able to use the settlement with Echostar as leverage with all the other MVPD's and ALL the other DVR makers TiVo was suing to extract settlements from them, especially compared to the full cost of going to court for the far more deep than pocketed (than Echostar) corporations that TiVo was also suing. And Tom Rogers and Charlie Ergen remained friends throughout the years long trial and court process and through the settlement. Never and "bad blood" between them.
