@NN: Glad you fond the requests solved to your satisfaction
. Thanks for the delay example: it looks like the delay is not per file or per subtitle stream, but can appear anywhere and only affects the subtitles appearing after it inside the same stream. The specs are not clear whether delays should be compounded (as in, if present, a second delay should be added to the first or not). I suppose it could go either way, and simplest would be not to compound delays. Have you ever encountered multiple delays in the same stream? Can you help me test the behavior of VobSub/vsFilter with multiple delays (I can't get it to work on my computer)? Basically, put in two 3-second delays a few subtitles apart and see if they're added to each other (resulting in a 6-second delay) or not. Thanks.
I think I can take care of the delay, while Zuggy fixes the blackness bug and some others he found. The new beta will be up in a couple of days.
