Sorry, I don't understand what do you mean by "marq subfilter".
I typically use VLC to play DVD MPEG2 VOB, and adding RSS feed, and a logo, an a text marq.
When I use all this functions with 0.9.0, VLC uses about 80% of proc, and about 40% with 0.8.6
If I disable RSS feed, 0.9.0 uses about 60%, and 0.8.6 about 30%
(today I have installed ubuntu, but it makes my windows partition crash
)
I will test VLC tomorrow, if you explain exactly what you want me to do
