Dell One review - skipped frames on blu-ray x264

The writer notes:

While CPU utilization was nice and low, sometimes the application would skip frames when decoding a movie. I informed Dell of my issue and they're working on reproducing the problem, I noticed the dropped frames on Casino Royale and Transformers, although Batman Begins worked just fine. See a common trend? Allow me to illuminate the situation. Both Casino Royale and Transformers use the H.264 codec, Batman Begins is a VC-1 title. This appears to be a NVIDIA driver or an application issue unfortunately newer drivers weren't available at the time of publication, so we'll have to wait on Dell to resolve the problem, although I'm quite convinced it's a H.264 decoding issue.

I have pointed that out before, but 1080p movie FILES (aka, mkv) in x264 using MPC-HC to use the video card card for decoding skip on my eVGA GTX260 SC.
I had to turn off video decode and play it with the CPU to get rid of the skipping.

I am getting a distinct feeling that the video decode hardware is simply not powerful enough for x264 1080 video, only for 720p x264 or for 1080 VC1.

Really...I thought the GPUs were better at that?

me too, until I found out otherwise... if i understand correctly, it does not decode it on the stream processors (which would just be driver issue), instead it includes special decoding hardware. Which is simply inadequate.
Or I am completely wrong. Bottom line is it does not work on the GTX260, it does not work on the one tested by anandtech, it just does not work (1080 @ x264 that is).

can anyone confirm or refute? can someone with more technical info (like anand writers) please explain what they think of this?
