Seeking is laggy with720p and 1080p wmv files

[meurglys0]

I have a new Dell XPS L502X with i7 2630qm, 4 GB RAM, GT 540M, Crucial M4 SSD. Windows 7 is the OS.

My problem is that seeking is not fluid while vewing 720p and 1080p wmv files with BS Player. Seeking with MKV, mpeg, avi, ts, m2ts... all other formats are fine, but with wmv files there's a very annoying 3-5 second pause before the video starts playing again.

I'd really appreciate it if someone could tell me how I could fix this?

Thanks in advance.
