So I've been struggling with my old iMac dropping frames on 1080p h.264 content in XBMC. CPU is not the issue, it never maxes during drops. Plex has always lent a helping hand with its Deblock filter option, and Boxee also seems to have it on by default. I've never been able to get XBMC to actually change this setting with advancedpref.

Plex let me down for a particular file (crash), and Boxee wasn't good enough. I messed around with VLC and figured out the setting that my iMac seems to hate the most, it seems to fix just about all 1080p content I have without too much noticeable quality loss. XBMC would be awesome with this setting for us old system guys... please educate me if I just don't know how.

VLC prefs: Input > Video Codecs > FFmpeg > Skip loop filter > Bidir

I hope this helps out someone else, I couldn't find this bit of info anywhere else.

<skiploopfilter>
This amount of the loop filter to skip on h264 decoding. This can help the performance of slower machines when decoding h264 content. Values, in decreasing CPU usage (and decreasing quality)
-16 None.
0 Skip only empty frames (default)
8 Skip non-reference frames (default on ATV)
16 Skip bi-dir frames
32 Skip all non-key frames
48 Skip all frames.

Tried that, no worky. Something I'm doing wrong?
