Getting frustrated now with openlp sadly, the issues are:
- mp4 video files not being able to load into a playlist, reports unsupported file.
- adding m4a audio tracks to songs is inconsistent, some work some don't,
- video file playback is often jerky and the video lags the audio, (both on old laptop and new laptop just got)
any common issues that would give these issues.
So at present, its a mixture of itunes, VLC and openlp to get a service running! not an idealsolution for those with limited computer literacy whom often do services.
