I converted my movie collection to mp4 and m4v files using Handbrake. I can watch them on my Windows 7 Media Center Desktop, but when I try to watch it on my Windows 7 Media Center/Media Player 12 on my laptop I get the error code regarding my sound card. Also, AVI, MPEG files play with no problems.
The movies play on my laptop using Quicktime, VLC, Media Player Classic...basically everything but WMP and WMC with no problems. So I can watch them but most importantly not through WMC.
I have an HP Pavilion DV4000 Laptop with SoundMax sound card running Windows 7 Ultimate
I have done the following:
1. Updated the sound card driver, ran a program to check for errors and found none
2. Changed the ID3 tags
3. Ran the drm update http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp
4. Downloaded different codec packages
5. Updated WMP and WMC
6. Taken Ownership as Administrator too
WHEN YOU RESPOND PLEASE DO NOT OFFER THESE SUGGESTIONS SINCE I HAVE TRIED THEM WITH NO LUCK:
