media player classic error: shows transparent subtitles: why?

[ciropizza]

hi all!

i have troubles with subtitles...
i use media player classic with Vmr9 (renderless) activated.
i have also installed vobsub that came with autoGK.

i'd like to view only the subtitles directly with media player classic and its "load subtitles" function, not the vobsub one.

suppose i have one file named "abc.avi" and one subtitle file named "abc.avi.srt".

if i leave all the settings as they are by default, i see like this:
http://xs110.xs.to/xs110/06486/zelig_Crop_over.jpg.xs.jpg (http://xs.to/xs.php?h=xs110&d=06486&f=zelig_Crop_over.jpg)
so, there are subtitles one over the other one.

then, if i rename "abc.avi.srt" so vobsub do not open by itself the subtitle file, i see like this:
http://xs110.xs.to/xs110/06486/zelig_Crop.jpg.xs.jpg (http://xs.to/xs.php?h=xs110&d=06486&f=zelig_Crop.jpg)

i try to change the subtitle style settings in mpc, but there's no way to obtain right subtitles.

moreover, if i disable vobsub when it has already auto-loaded subtitles, all's well.

why this happen?

thanks in advance,
ciroops.
