tested on frenz's HD Pro, pixelized occurred on Transformer1

For Transformer 1....99% media players out there got pixelization...the encoders screw up the movie by doing dunno how many reframe rates.

Most of the time, you just need to remux it.

I have 720p (deleted), 1080p, and BDISO versions of transformers 1... but both WDTVLIVe and BD1 all played fine and did not notice any pixellated issues - the so called pixellated means we will see distorted areas filling with square boxes with colors is that it? rclxub.gif

Hi guys, I'm newbie here biggrin.gif
Right now, I've 42" full HD LCDTV and many Japanesse anime collections with SD quality.
So the questions is what NMT (chipset) should I choose best for upscaling SD quality movies into 42" full HD LCD without showing too much artifact? icon_question.gif
My guess is all NMTs with Sigma Design chipset inside it, but stiil I need confirmation from who had experienced it. icon_idea.gif
Regards

Hi guys,

I gotta question too. I just got my Popcorn Hour NMT yesterday. Love the speedy open-sourced interface.

After some testing, I got shocked that my unit is capable to play some RMVB files!

Can it be considered as a bug? tongue.gif .... AFAIK, Sigmas dont play RMVB hmm.gif

I think Realtek PQ is better than the Sigma, but if you want the advance HD player, I think Sigma is the only one here, at least Sigma is a proper HD chipset for audio visual. Realtek, is also consider HD chipset, just the HD audio is the down side, can't even support a single HD format.

Guys, I got a question...

The new Xtreamer is now comes with Sidewinder heatsinks and without fan. How do I know if the chipset inside is RTD1283 DD+ ?

it's the other way around.. Sigma gives better PQ especially for BD iso/H264.. realtek got HD 720p rmvb..

Finally had the chance to test a Realtek based media player.

Things to note, I found that the media player clipped both black and white. On this particular media player, there was no choice to change colour space, so no way to see if it can be fixed. There was no colour decoding error that was the positive part (but this is if u do not touch the internal settings). Unfortunately, there is some sharpening out of the box, even if u turn the sharpness on the display all the way down.

Because of the clipping the peak whites cannot hit as high as the display would allow. Another negative point, was that the image was shifted by about 2 pixels bottom and left. I did not know if there was a hidden feature to shift the image. So, if ur display does not have a way to shift, u will lose some info

There are differences between the Sigma and the Realtek chipset. Until I see the new RTK chip, I cannot conclude if these bugs have been fixed.

I'm not that technical but I hope I understand that what you meant by the white clipping. I've experiencing a "shadowy" white color in my POHD when watching scenes that have a very bright highlights e.g clouds, the white color is not pure white but instead very blur type...

In extremely bright white scenes or colour scenes, if the player clips before digital level 235, u will lose details. U can reduce this effect by proper calibration, and there is some evidence that there is content that seems to go at least until digital level 240. Of course, clipping can happen anywhere in the display chain, but in this case I'm sure its the media player as the display had no clipping tilldigital level 252.
