Description

Hi, this is my 1st issue reported here.

A few weeks ago, using Showtime 3.99.41 on my PS3, I try to watch a groups of videos (Game.of.Thrones.EXTRAS.BLURAY.720p.x264.DTS-TvT), with same special specifications:
- Video: 720p
- Subtitle: Sup-PGS, extracted directly from BD, with 1080p resolution.

View the subtitles was impossible (try 720p and 1080i output signals), and finally I have to do this steps:
1) Extract the subtitles using MKVExtract.
2) Rescale the 1080p subtitles to 720p, using BDSup2Sub
3) Merge the 720p video and the new 720p subtitles with mkvmerge.

I also download another version (Game.of.Thrones.S01.EXTRAS.BluRay.1080p.DTSHD-MA.h264.Remux-decibeL), with 1080p video and 1080p subtitles, and works fine.

I hope that in the future, Showtime can scale this type of subtitles, if the resolution is different from the video.

Note: The upload process don't work. Because of that, I upload the files here:

I did some tests with the original files (mkv720p with internal 1080p Sup-PGS subtiles), using latest version (4.3.311).

Works ok, but only if the subtitle lines (or text) are at the lower part of the image (in other words, if they are not visible without the scaling process). The issue its still present, if the text lines are at the top, in this case the subtitles are not scaled.

A definitive solution could be to scale all this kind of subtitles to the video resolution.

Yeah I completely misunderstood that it was possible to extract the video dimensions from the subtitle track itself. I'll fix that.

Now, with 4.3.313 works ok... Thanks a lot for all your time and efforts
