I can't see you'd have runied them - if you haven't edited them

It really sounds like something isn't able to cope with the processing/bandwidth HD requires - it could be the harddisk disk or even the video system (or even a driver issue) - I have had problems playing HD in full screen mode, yet it plays OK on a reduced window

edit: actually I think it might have been the otherway round - at full screen only using 9% of cpu but in window seeing 40% on a i7 cpu

Are you thinking of viewing High Definition (HD) video in your PC? If yes here is the minimum system requirements for playing HD video using Cyberlink HD Video playback software ( I guess most of us won�t be able to meet it):
Processor (CPU):

* Intel Pentium EE 840 (3.2 GHz)
* Intel Pentium EE 955 (3.4 GHz)
* Intel Pentium D 9xx series 945 (3.4 GHz), 950 (3.4 GHz), 960 (3.6 GHz)
* Intel Core Duo T2xxx series T2500 (2 GHz), T2600 (2.16 GHz), T2700 (2.33 GHz)
* Intel Core 2 Duo E6xxx series E6300 (1.8 GHz), E6400 (2.13 GHz), E6600 (2.4 GHz), E6700 (2.66 GHz), E6800 (2.93 GHz)
* AMD Athlon 64 FX series FX-60 (2.6 GHz), FX-62 (2.8 GHz)
* AMD Athlon 64 X2 series 4200+ (2.2 GHz), 4400+ (2.2 GHz), 4600+ (2.4 GHz), 4800+ (2.4 GHz), 5000+ (2.6 GHz)
* AMD Turion 64 X2 TL-60 (2 GHz)

Note: All the above CPU�s are Dual Core.
Even my Dual core Pentium D 930 @ 3.0Ghz is not enough.
System Memory (RAM):
512 MB or above, 1 GB is recommended

Disc Drive:
Blu-ray Disc drive or HD DVD drive

Graphics Card:
NVidia GeForce: 7600 GT, 7800 GTX 512, 7900 GX2, 7900 GTX, 7950 GX2
ATi: X1600 series, X1800 series, X1900 series
(Again I fail this condition as am currently on onboard graphics powered by Intel 945G chipset)

Video RAM:
256 MB graphics card memory or above

Display Devices:
1. HDCP (High-Bandwidth Digital Content Protection) compliant display (DVI, HDMI connections) for digital output.
2. TV (composite, componet, S-Video) or computer monitor (VGA) for analog output


Cyberlink even offers a tool which will check your system for compatibilty and will give a report:

Note that those specs relate to playback of BluRay or HD DVD. What video format does an HD camcorder use (H.264 maybe)? What resolution (camcorder? monitor?) are we using here?

Are these camcorder specs the same video formats (codecs) and resolutions as BluRay or HD-DVD?

Also note the requirement for a half decent (not integrated) graphics card, which may or may not be present on a laptop.

We haven't yet been told what graphics is in the OP's laptop, nor do we know exactly what CPU it has.

Lets go back to basics -- Try updating graphics card driver to latest. Try getting all windows updates and downloading latest windows media player (as this will likely contain updated codecs)

Let me gather all the info required, update all the necessaries and I'll report back when all is complete.

I'm finding this quite interesting

All done: so a recap: -

Laptop Esprimo M9400 with XP Pro, 80Gb HDD; 3Gb DDR2 Memory; Centrino Duo CPU T7250 2.0Ghz; Intel Mobile 965 Express Chipset and finally, Windows Media Player 11 with K-Lite codec pack full installed; all updates are installed and active.

Won't play HD video clips of between 80 / 100Mb without jumping, freezing or blocking.

Thanks for the nearly complete update.

The resolutions (in pixels) of the HD video and your current display adapter settings are still unspecified...

Not sure I understand this question, but the video was shot in 1080P or on the high res as the camera would allow on an 8Gb SDHC card, using a new Samsung Bullet style camcorder.

And I think you mean 1280x800 on my laptop

Thanks, that'll do nicely.

You should probably follow the earlier advice about ensuring graphics drivers etc are up to date.

The 1080p probably translates to 1920x1080 in PC graphics terms.

You'll note this isn't the same as the 1280x800 on the laptop.

So either something has to rescale every frame before displaying it (a non trivial task), or the PC display has to change resolution so the HD video doesn't need rescaling.

Rescaling every frame in real time can be done either by a decent CPU or by a decent GPU. It's quite a lot of work and *may* be more than a laptop CPU or GPU can cope with (lots of variables here so a definitive should/shouldn't is tricky). On the other hand it isn't exactly bleeding edge either, a decent CPU/GPU combination should cope fine.

Anyway, as you seem to be maxed out on one core, it sounds like the CPU is being asked to do more than it is capable of doing. Make sure the GPU is doing as much as it can (the "hardware acceleration" slider mentioned earlier).

Or avoid the rescaling altogether by changing PC display resolution. You probably won't get the required resolution on your laptop's built in screen but if your laptop will support a 2nd monitor (is it an Intel Graphics Mobile Accelerator 4500?) you could see if it works with that set to 1920x1080.

Can you try playing the stuff back on a latest greatest PC with decent graphics (not some Intel integrated stuff)?

You could also try a video editing tool of some flavour to reduce the resolution of the files to something you PC can directly display without rescaling, and see how that goes.

Your files *should* still be intact; displaying them in WMP or MPC should not cause permanent problems like this. Can the camera play them back to prove this?

What a great post, thank you - unfortunately the camera has gone back so I cannot check that out but I will find a super PC in the near future and see what occurs.

Thanks again, Blue
