What is the *current* 30,000 foot view?

Why are you majoring on SD? It's old news. The SD upscaling of the Sigma chips is not great, its one of the areas where VXP processing should assist greatly. Although please do explain yourself with regards video_ts being unwatchable due to colourspace settings as that one has left me mystified, we even have colourspace options now in settings?

HD is where it's at these days. Watch any MKV on the 100 series and then watch it on the 200 series and you should see a difference. Like I say even the Mrs and the kids (18, 20 and 22) independantly commented on how much better the picture was. They don't come any more independant than the Mrs and kids

Why do you have this feeling that Nvidia produce such great quality picture output? Remember their last chip the Tegra and all its claims that were found to be wanting?

The black levels are incorrect on VIDEO_TS folders on the A100 the last time I tried them out (about 2 months ago, before the latest firmware that got WebDL working). All the colours looked washed out. I'm not sure why that has you mystified. Everything seems to change when you go into 'dvd mode' with the A100.

I'm still asking and getting no answer - why does the 200 series have better HD decoding than the 100 series? There's not a whole lot of scaling going on which is why I was mentioning SD as that's the only way I can see some sort of advantage. What are the technical reasons that H.264 output from a newer Sigma chip is better than the old one? As I keep saying I SEE NO DIFFERENCE. I don't know how many times I need to repeat it but this is my last post in this thread.

I am saying that decoding a file by a HTPC it doesn't matter what the graphics card is, as long as the decoding gets done the quality is equal. Although you can of course mess things around with post processing, colour space etc. What has the Tegra got to do with the Ion?

Your family can say what they want, I have no idea about your settings and would like some objective evidence not personal interpretation otherwise it's just all opinion.

Guys, maybe I should have started this thread with a different title:

"What is the state of Open Source Development w.r.t. Sigma Design hardware (these days)."

See, I would like to use the Sigma Design platform for all kinds of things. But the last time I looked into developing software on this platform - it was (very) clear that we were not going to be told how to handle the video hardware.

That left us with an ARM processor running Linux. Well ... shoot guys (& gals) ... you can find that in a dozen other networked devices at a fraction of the price (of even a used NMT).

So ... is everyone just running the provided (canned) software ... or did something amazing happened and now there are offerings the likes of XBMC or MythTV or SqueezeCenter or Roku or ...

-thanks

xbmc was announced for a sigma chip but dont get all excited it wont be open source for the sigma libs. sigma is still closed and need a copy of the sdk to do anything.
