Well i was calabrating too soon. When i mux the subtitles, they play well but the new movie file that is created after mux process is twitching (i hope i used the right word for that

) . It is not playing flawless.
The same thing happens when i play it on my Pc, so i think it's related to the MKVMerge. Is there any other option in the MKVMerge that i need to check/uncheck to awoide this problem?
I also noticed that i don't need to mux subtitles when i play DivX movie.
All i have to do is to rename the SRT file and give it the exact name as the movie, put them in the same folder, run the movie, and then press the OPTION on the TV remote, and choose subtitles and then i have the srt subtitle witch can be shown on the Tv. Only thing with this is that the subtitles are small, and it's little bit hard to read them. I don't have any option on the Tv to make them larger. I own tx-p42g30e (Europe) model.
When i mux the same title the font is "normal" sized, but when i play them without muxing thay are to small. And that probably means that the Serviio shrinked them. Are there any optin that i can change to make them larger?
I play all my movies without transcoding.
This is the info how to play muxed subtitles (if someone needs it at all

)
I run the movie and all i need to do is press the OPTION button on my remote and in the menu that appears i can choose subtitles and after that in new menu i have ali muxed subtitles in my movie. In my case i had two, English and Croatian, and they booth worked well. Font size is ok. They are not shrinked. And the Croatian special alfabet signs (šđčćž) are encoded right. No problems there.
