I read the Hometheaterhifi review of the 970 and there were a couple lines I found confusing.
"While it wasn't quite to the level of popular solutions like the Realta HQV or Faroudja DCDi, it did a very commendable job with the lines." and "Overall, I would say the Mediatek did an above-average job in our de-interlacing tests for an all-in-one solution, but it still does not live up to the bar set by the higher line video processing chips out there now."
That makes it sound like the deinterlacing isn't as good as DCDI, but yet they gave the 970 the same score as the 2910 which uses DCDI. Does that mean that Denon implementation of the DCDI chip in the 2910 wasn't as good as it can be? But the best examples of DCDI are better than the 980h?
