HP TX 1000 Series Laptops with Nvidia 6150 and ITunes Videos in Quicktime

I downloaded a movie from Itunes recently and no matter what I did, the movies refused to play back on my HP TX 1215NR laptop. It would start playing but then Quicktime would crash with some kind of BEX event error.  Right before the crash the movie would get pixelated and distorted and then crash.  At first I suspected it was the NVidia 6150 video drivers which are custom made for HP and promise "HARDWARE H.264 playback".  

Because of the ANNOYING DRM apple puts on the movie, I could not even try playing it back in anything other than Quicktime, so I thought maybe its just the Quicktime Player having a hard time with it. 

I looked for a solution for months, but finally after searching some forums I ran across this solution, and it wasn't the video driver, it was the SATA HD driver!

1. Right click "Computer" and select properties.
   
2. Open IDE ATA/ATAPI Controllers.
3. Loctate the NVidia controllers.
4. Right click it and select Update Driver.
5. Click "Browse my computer for driver software".
6. Click "Let me pick from a list of device drivers on my computer".
   
7. Ensure that "Show compatible hardware" is checked.
8. Select  "Standard Dual Channel PCI IDE Controller".
9. Open "System Devices".
10. Select one by one each of the NVidia Items, and repeat the above.
11. This time Select "Standard PCI Ram Controller".
12. When you are done, you will have 2 nVidia controllers left that don't have standard components. Thats ok.
13. Restart.

After you restart your laptop should be able to play the content w/ no problems!  However, my laptop was just plain not able to keep up with the HD movies, but the normal res movies ran fantastic after this.

Goodluck!
