All 3 major commercially available display formats have their issues, pro's and cons. There has never been anything with 100% display satisfaction. And there never will be any yet,not for this moment. Except CRT if you can still live with it and the size limitations. Use a 14" CRT and the PQ will be surely fantastic if you get what I mean.
If ever there are any format commercially available that is 100% without any issues then tell me and I will definitely buy it if the price is right to me. I have used all 3 formats and will continue to seek a 4th format.

Astro is only displaying analog video so you should expect analog type of quality. But not all channels are bad and some channels are preety good but definitely not yet to HD resolutions.
