Default BSplayer, subtitles & processor load

Hi!

I've tested some movie players and found that BSplayer has a lower CPU usage (even than Media Player Classic), BUT... only when no subtitles are shown on the screen.

I've tested with almost all combination (with or without) of following: DivX, XviD, ffdshow, overlay, non-overlay, BSplayer 1.22 build 817, BSplayer 0.86 build 501, VobSub, various screen resolutions.

Then always when a subtitle text is shown on the screen, the processor usage will rise to 90-100% (I have a Pentium 4 @ 2 GHz).

To resume (very briefly) my testing:
.......................................... CPU Usage (%)
Media Player Classic ........... ~ 45% (no noticeable rise when subtiles are shown)
Windows Media Player 9 ....... ~ 48% (no noticeable rise when subtiles are shown)
BSPlayer 1.22 ...................... ~ 30% (no subtitles) and 90% (with subtiles on the screen)
BSPlayer 1.22 (/w "force RGB") ... ~ 48% (no subtitles) and 100% (with subtiles on the screen)

Why?

What should I do to have BSplayer behave normaly and have less CPU usage when subtitles are on the screen?
