subtitle margin width does not work on TV mode

[a]

Hello,
I am running BSPlayer 1.1 on windows XP.

I am experiencing the following problem.

I use the subtitle renderer of BSPlayer and when I play the file
on the TV, the configured subtitle margin width is not taken into account.
The result is that most of the subtitle are cut at both end.
However, it is taken into account on the monitor.
I tried to check and unckeck the box "do not apply margin on primary display", but that does not change anything.

Which is weird is that this functionality was operational on a
previous version of BSPlayer (but I don't remember which one).
However, rolling back to 1.02 does not solve the problem.

Does anybody have a clue on a possible solution.

Thanks,
Arnaud.
