How to test for the error, what's the expected result and what do you see?
Can you reproduce the error with latest FFmpeg?
Also please show complete command and log, consider using -report.

As I am intrested in this report
cehoyos, can you briefly explain question asked by saste.

When I run(decode using ffplay) the clip attached here, i see only problem is "Help"(subtile) having green color.
I dont see any error message while decoding at my place.
I just wanted to know what do we expect from dvb decoder or encoder.
This report shows only "we have error", what error is, Is it red colored error message or something unexpected at output. if output is different with other player or decoder then in what sense. which player did we checked to compare output.

He apparently missed my question.

Replying to cehoyos:

The problem is related to the first text displayed by ffplay, the "help" word which looks corrupted (probably an alpha issue).

I thought that the first subtitle is just incomplete (or damaged). Some media players probably prefer not to show damaged subtitles but FFmpeg (default!) behaviour was always to show everything that can be decoded. After all, "help" can be read.
If this is really the issue (I don't know), "help" should not be shown for -strict strict.
