MPEG with PCM audio will offer now only option to demultiplex

- Fix for jumping subtitles. The position on screen is now calculated by the absolute line, so a subtitle with only capital letters (AAAA) will remain on the same line position as a subtitle with only small underlined letters (pppp). See example. Because subtitles normally use combination of all kinds of letters you may not actually see this problem very often.
- Subtitles imported from bitmap will be not trimmed anymore (it could have the same jumping problem as above). If the imported bitmap is a full D1 size then the margins will be ignored, otherwise the margins will be used on the original - size bitmap. This should solve few troubles with positioning.
- Open GOP warning can be disabled in Properties.
- Open GOP warning is now always disabled on a files < 4MB (transition files etc.)
