I have been having the same issue.
I have tried from 2.4.0 all the way to 2.5.6.
When ever I add the VobSub and try to encode (codec doesn't matter) it crashes.
Some versions it would crash during the preview, other didn't.
I noticed that if I have the encoding start at from 78, it didn't crash at the beginning, but would crash around frame 1920.
So, anyone have any ideas/solutions to this issue?
Has ANYONE ever been able to successfully use this filter?
On a side question: why was the filter removed from 2.6.0+?
I know version 2.6.0+ is timecode based, instead of framed based - but so are these subtitles.
Thanks in advance.
