The video doesn't play well in a machine with dual-core mobile CPU AMD Turion X2 TL-58 and NVIDIA Geforce 6150 Go. The CPU is 100% and there are framedrops. Is there a way to play this smoothly ?

It can play on Netbooks, provided they use nVidia's ION(2) platform.

Core AVC requirements make it pretty clear:

1080p video at 24-30 frames per second

CPU - 2.8 GHz or faster Intel Pentium 4 or equivalent AMD processor

RAM - At least 1GB of RAM

GPU - 256MB or greater video card

OS - Windows 98, 2000, XP, Vista, 7

GPU Requirements for NVIDIA CUDA:*

NVIDIA GeForce GTX 260/280/290/295, 9800, 9600, 9500, 8800 GT, 8800 GTS 512, 8700, 8600, 8500, 8400, Tesla S1070/C1060, Quadro FX 3700, Quadro FX 3600M, Quadro FX 1700/FX 570/ NVS 320M/FX 1600M/FX 570M/FX 370/NVS 290/NVS 140M/NVS 135M/FX 360M/NVS 130M and higher.and higher.

You will also need drivers 191.07 or higher from NVIDIA.

So for your netbook, there's no way to play it smoothly, you probably will have to re-encode the file to a lower resolution to 720p (1280x720) perhaps.

what do i use to transcode from 1080p to 720p so that it can play on my netbook:Acer Aspire One AOA 150 and also the Hp tablet? –  iceman Jul 31 '10 at 10:38
    
You can use a software like SUPER or Koyote. Have a look at this question: superuser.com/questions/156799/… –  Sathya Jul 31 '10 at 10:53
