m1330/m1530 Hi Def Playback Performance?

Im on hour 26 of my new m1330, and have been very dissapointed with the ability to play 1080p content. I'm actually somewhat confused at to why it isn't playing smoothly. a sample wmv9 movie plays smoothly at 1080p. Other downloads i have are 1080p .ts blu-ray movies, they really play really glitched when enlarged to full screen. Which confuses me because i would think they'd require the same amount of hardware to play minimized. Can anyone please comment on their performance playing back hd with either of these notebooks, using an hdtv or another hi-def monitor, and what kind of content. Mine is currently plugged into a 24" 1920x1200 monitor via vga, because the hdmi doesn't play nice. I have 169.09 drivers installed, perhaps i shoudl be using other drivers? Am I just being too ambitious for this little lappy? What really baffles me is that I can play a .ts file like casino royale which is 32gb, in powerdvd 7, and it has the cpu at 30-40% load, and it stutters like mad, or if i play it in wmp the cpu load is 80-100% and it plays a little bit smoother. How can that be, the lower cpu load should mean its getting offloaded to the gpu and should play smoother, no? other notables, I have a vista codec package installed, I used to have a desktop with 2.4ghz c2d & 8800gtx, which played these no probs, with seemingly no assistance from the gpu. my current rig m1330 2.0ghz c2d 8400gs. Thinking of sending this back for a higher powered m1530, hoping someone can set me straight. Plus I'm just generally curious about peoples experience playing hd with laptops, it seems hard to find conclusive threads about it.

 

I playback HD-DVD with PowerDVD Ultra and it works fine for me on the laptop's monitor. I'm going to try HDMI to my projector and TV soon. Since you downloaded, are you sure the glitches you see aren't in the files?

 

Thanks for the reply. Yeah the files are probably less than Ideal, but they ran perfectly in my old beast of a desktop. I'm really interested to hear about your playback through hdmi, are those hd-dvd discs ur playing, or files?

 

OMG OMG I figured it out. If I turn of aero in window color and appearance, then its completely stutter free. Is it just a resource hog? Whats odd to me is watching the statistics from powerdvd, its locked at 20mb per sec regardless of if its full screen or a smaller size, but it only stutters when it enlarged to full screen when aero is on. Well thats cool that i figured it out, but i do kinda like aero, is there some way to have a specific program turn aero off and then back on after it closes?

 

For my M1330 I'm using the Xbox 360 HD-DVD drive, ripping HDs to .ISO with ImgBurn, and mounting with Daemon Tools to playback with PowerDVD 7. The new PowerDVD 7 doesn't allow playback of HD disc rips from a folder.

But on all my computers, Power DVD 7 Ultra always automatically turns off Aero and switches to basic when playing back HD-DVDs. I guess what you're seeing is probably the reason. Not sure why yours isn't doing that.
