hello. i'm new to this so apologies if this question's been answered before.
I have several files in TS format (720x576, 8000kpbs, 25 frames sec). they are all playing fine but quite noisy/grainy on my machine (netbook- dual core atom, 1gb ram).
However when I play direct from my Hdd to 42" HD tv they play fine with no grain at all. Shouldn't this be the other way round if anything? I'm using mpc hc with core avc but it's same on other players as well. Would it have anything to do with bypassing the players when I go from HDD to tv?

short answer.. all hd tv's have build-in (NR) noise reduction. different brands have varying degree (quality) of NR. there may/may not be adjustable controls on some of them. i myself prefer the noise, if thats what you want to call it.
imho, best to leave the videos alone.
A 720x576, 25 fps video encoded with h.264 at 8000 kbps isn't likely to have much in the way of encoding artifacts. That means the actual video was full of grain before encoding. And, of course, the job of the encoder is to preserve what its given as best it can. That leaves noise reduction on the TV as the most likely reason you don't see grain there but do see grain on a computer. Your graphics card probably has video noise reduction features. So try looking through the graphics card's setup applet and enabling them. For example, Intel's applet:
Many players have their own image processing options too.
Another thing to keep in mind: sharpness can increase noise. So if you have sharpness setting cranked up you may need to lower it. Or switch to an "edge enhancer" rather than a sharpener.

yes vhelp looks like your correct - upscaling on pc and pc monitor = crap, hd tv upscaling = good. there it is chaps.
