Pixelation in screenshots, if jpeg is set

Hi,
I have the error of mosaic like pixelation when I make screenshots in jpeg of HD-ts files.
If i make them in png everything is ok.
That only occur when I screenshot my HD-TV Ts-files. low-res content is fine.
And only when jpeg is set as screenshot file format.
That error was present with an Ati 4850 card and even now with a Nvidia GTX470.
It persists in the new 1.1.0 build too.
I use Win7 x64

The issue is just with higher resolutions?

Yes. I made screenshots of a PAL avi and a PAL Mpeg and there is no issue with jpeg screenshots.
But again on my fullHD TS-file from my Satellite HD Receiver i get those mosaic layer on top
Screenshot one is a jpeg of the trailer Rio published by the Apple trailer website, you can see the mosaic
And the second shot is from the ts-file recorded by my HD-receiver, there you can see the mosaic better.

I can't I can only try PAL FullHD oh and I could get a 720p trailer as well. I will report if the error occurs on 720p too.
I think below 720p it starts, because at 720p there is a little mosaic too.
Form your opinion with that 720p screenshot.

The 720p Video was this trailer.
http://trailers.apple.com/movies/sony_p ... _h720p.mov
The 1080p was my own recorded file:

I can't make shorter snippets, I have no software to edit the 1080p-TS-files.
And 1080p Trailer:

Thanks as well.
But actually I use Win7 x64 and not Win32 bit.
