Problem with fullscreen HD playback on 2.5.7

[AndreiTV]

Hey BS-player wizards,

I am also finding this issue with the latest release. I haven't yet tried the downgrade to 2.5.6 but have found that if I stretch the movie window to the same size that the full-screen takes, I don't see the issue.
For me, it behaves somewhat along the lines that the movie stutters, repeating approx. the last second for maybe 10-20 seconds at a time. The player"catches up" and plays well for a period of time and then may do this again.

Movie specs:
X264 MKV
System specs:
Windows 7 64bit
Intel Core 2 Duo (E6850)
XFX Geforce GT 8800

I've read somewhere that it may be an issue with the MKV specification, but I don't want to throw buzz words about stuff that I don't fully know how it works. The indication was to read:
Compressed Headers | Matroska
and download an mkv clean package.

HTH.


>>> Quick update, full specs for a movie that has the same problems. Apologies for the unnecessary parts.
