HD .WMV files lagging?

[BlackScarletLove]

When I play large WMV files, (3G 1920x1080) the video lags for a second every 2 seconds, and the memory usage for the media player goes up to over 1,700,000 K.

This only happens on wmv files. I can play 8G 1020p high resolution mkv and mp4 files with no problem, but can't play hi res wmv files. Any ideas?

These are my specs:

Install SP3 for XP or upgrade to windows 7.
Remove K-Lite codec pack

Download either Download Media Player Classic Home Cinema, Free Video Player Download and http://haali.su/mkv/MatroskaSplitter.exe

or to make life easy for yourself this CCCP - Combined Community Codec Pack

turn off any WMV acceleration in your radeon drivers - mpc-hc will hardware decode for you or if using CCCP it will software decode.

hey it friggin worked!

I updated windows, and also replaced my codec pack.
What was the likely solution, SP3 or CCCP instead of K-Lite? Or both?

 

[LordOfLA]

Most likely disabling hardware WMV in your drivers. Second would be switching to CCCP as K-Lite installs many codecs a large portion of which conflict with each other a lot of the time.
