Recently I upgraded the vompserver plugin to not override in-progress recordings by playing a live channel. This dongle detects when the plugin has refused a live channel and displays nice messages rather than freezing for 10s and displaying a lot of black.
Also in this plugin is a fix for chasing playback. You have to be more than a minute behind but it's better than it was before.
If you upgrade to this plugin you will need to update your vompserver plugin.
