UTF-8 Subtitle causes Lag Vobsub fails to Work

[GoogleCodeExporter]

UTF subs causes same 1/2 sec Lag
Vobsub doesn't work at all.
ASS sub also causes lag but rarely 
not at beginning but start to lag later on i the middle but not constantly

I cannot open the link in Comment 1, megaupload.com may also be blocked for me. 
And I don't really get the issues either. By UTF subs, you mean ASS subtitles 
saved in utf-8 encoding format? Or is there a typo and what you really mean is 
USF subtitle format(http://en.wikipedia.org/wiki/Universal_Subtitle_Format)? 
For the former, I use UTF-8 encoding subtitles quite a lot and never encounter 
any UTF-8 specified *lag* problem. For the latter (and also the Vobsub not 
working problem reported), I know little about other subtitle formats except 
ASS/SSA. In fact, vobsub format is handled in a totally different rotine from 
ASS/SSA. A quick test on a pair of Vobsub files works fine. So the problem you 
have with Vobsub format is probably script specified, can you upload the Vobsub 
files? 
For ASS sub lag issue, it almost certainly is script specified. Without the 
related script, I can do nothing. Set sub-pixel positioning to NONE may helps 
(http://code.google.com/p/xy-vsfilter/wiki/NewConfigOptions). 
For changes not apply issue, I think I've got it, unconfidently though. I'll 
try to fix it.

i don't know anything about UTF-8 subs 'cuz i main use vsfilter for rendering 
only
its probably ASS subtitles saved in utf-8 encoding format like you mentioned
mpc-hc shows it as UTF-8 sub in its "Properties"
for vobsub you can add codes from this new mpc-hc version of vsfilter.dll 
http://www.embedupload.com/?d=1NAHIHNHUW
VSFilter 2.39 is from old mpc, isn't it?
new ver is 2.40.3644 from mpc-hc that i uploaded here.

for megaupload block issue
you should try changing your dns to google dns
it doesn't block websites like ISP/gov does

ASS subs lag occurs only on fast scenes but not often
so its not too big of issue 
lag issue is is pretty much minimized in current vsfilter 2011/10/03
so it is pretty much hard to notice 
but at fast scenes UTF/ASS subs lags becomes bit easy to notice.

Sub-pixel positioning enabled positioning a text/shape in fraction of a pixel, 
e.g. with 8*8 sup-pixel positioning support, text/shape can be positioned at 
13/8 pixel to the left edge of the video frame and 9/8 pixel to the top edge of 
the video frame. While without sub-pixel positioning support, fraction parts of 
the position are ignored, e.g. positioning at (13/8, 9/8) pixel will be treated 
as positioning at (1, 1) pixel, and cache efficiency gets improved due to this 
simplification.
See

=NewConfigOptions for more examples.

subpixel set to none
lag issue reduced but doesn't completely goes away
screen still freezes once ~3/5mins or so.
