Daniel, I have finished the greek translation, you can find it here
But I seem to have some issues, though:1.
There is an option in the program: "Play your playlist in loop mode!"
This does not appear in the .pot file. The translation is: "Αναπαραγωγή της λίστας με επανάληψη"2.
Under "Help" -> "Mplayer shortcuts", the first entry (seek backward/forward 10 seconds) does not appear translated in my system (I have copied the .mo file to /usr/share/locale/el/LC_MESSAGES. All other entries are translated except this one. When I edit this entry with poedit, some strange symbols appear:3.
Another entry that doesn't display in Greek is "Converter ffmpeg is installed", again under the "Help" menu.4.
Finally, when I want to delete a video, either from the disk or from the playlist, a warning message appears. This message is not in the .pot file.Message:
Are you sure you want to remove (some file) from your playlist?Translation:
Είστε βέβαιοι ότι θέλετε να αφαιρέσετε το αρχείο (some file) από την λίστα;Message:
Are you sure you want to remove (some file) from your drive?Translation:
Είστε βέβαιοι ότι θέλετε να αφαιρέσετε το αρχείο (some file) από το δίσκο;
Check the files I send and tell me what you think.
I have provided the missing translations in case you want to add them yourself.
I don't know why some entries are not in the .pot file... Do you have a newer one (for the newer version)?
