The third beta brings improved VLC support (thanks Darkman802) and more options on how Syncplay should handle unpause events. If in the main Syncplay GUI menu bar you select ‘Window’ -> ‘Show auto-play button’ then you can also enable the ‘auto-play when everyone is ready’ feature. The ‘a’ part of the release tries to fix some minor issues with VLC seeking unnecessarily.
