Any way to get my laptop to play 1080p h.264

So I bought a Wind U230 a couple weeks ago, and it games and plays 720p movies just fine, but even with CoreAVC I get an occasional stutter or audio hiccup while watching 1080p movies. Now I'm wondering if using a codec that uses my ATi 3200 would make this possible (even if it's a less efficient codec I hope the power of the 3200 would outweigh that, but I can't figure out how to enable GPU acceleration. (I'm using Media Player Classic, but would be happy to try other players) Can anyone help me? Google isn't being my friend.
 
A laptop display has a finite native resolution. That cannot be exceeded. The Wind 230 max is 1366x768 pixels. How many "p" is that? 1080p is 1920x1080. 1080p movies should play nicely at 720p.

yeah, that's my problem, I know it'll downscale to 1366x768 (unless I plug the HDMI into my TV) But I get everything I describe while trying to get it to play in native rez. on my wind. I only have a couple of TB of storage space, I can't afford to have every movie in both 1080 and 720. even if the actual video quality is only equivalent 480p (I'm not a videophile) I want to be able to watch any movie I have on my laptop. For some reason I can't get 1080 to downscale and play at 1366x768 without stuttering.

What are the other specs on the laptop?
OS?
CPU type?
CPU speed?
RAM amount?

That GPU should be sufficient to handle 1080p playback. My roommate's old MacBook Pro (2GHz Core Duo, 2GB RAM, x1600) could play 1080p pretty well, so if you have the CPU for it, yours should.

What file type are the files? You are using CoreAVC, but have you tried other programs?
 
this is an Athlon Neo MV40, a far cry from being remotely capable of handling 1080p AVC on x86, even with CoreAVC. although 1080p video is capable of "downscaling" I'm quite sure that this is carried out by the renderer after encoding is finished and you will still need a far more robust system to do it smoothly. the Wind U230 is like a K8/Radeon-based ION-type netbook and although it's faster than any Atom CPU, it cannot be relied upon for decoding at 1080p, at least not at 1.6 GHz.

what do you have is a radeon 3200 that can decode the video, but you need to be using a dxva-enabled decoder like PowerDVD, MPC-HC, etc.

um, sorry, wind U230-040US. L335. 1.6ghz K8 X2. I get the feeling I'm doing something wrong (and looking like a total noob) but I've never had to use GPU acceleration before, I've either had desktops that could B****slap it on CPU power alone, or laptops that wouldn't survive the whole movie on battery power. So I'm lost.
 
Radeon HD 3200 requires a mid-range dual core CPU to play advanced 1080 HD formats without glitching. A discrete HD 4350 has problems when paired with really low-end CPU.

You can play an encrypted bluray on a 1.8 GHz sempron perfectly smoothly on 780G as long as your cyberlink or other DXVA decoder is properly configured. A dual core will lower utilization but that is by no means a requirement. An unencrypted mkv or similar should be fine on a 1.6 GHz dual core.

Sorry, I meant to say the HD 3450, which is the same GPU used in the 780G, not the HD 4350. And numerous reviews found that the discrete HD 3450 with dedicated memory struggled to play advanced 1080 formats/content without glitching on a low-end CPU. The 780G could hardly be better, given that's its the same GPU, but with the liability of being integrated with shared memory. I suppose SidePort memory implementations probably have better results, but even that is inferior to having 512MB of dedicated memory in the discrete HD 3450.

the decoding isn't memory limited, it's compute limited and it can be done without the sideport, on any radeon-3000. the most recent article i can find is from toms, but they had it running fine using less than 50% CPU. i mean if a single-core Atom can do it with a gf9300, then a dual core K8 can do it with a 3200. just follow beginner99's link and make sure everything is set up right.

some people expect it to work magically without any advanced configuration, and I can't explain why.
