That's the point!
svn's are for testing and are of varying reliability. They are not intended for production use...i.e. Do not use svn versions if you are relying upon the system for functionality.
My point is this current sequence of SVN's have gone from flaky DVB radio to barely working radio that crashes the rest of MP when it fails on this weeks train wreck release. Not much point fixing all the playback annoyances if the recording engine keeps getting worse
There are really small amount of DVB radio users, that probably contributes to the bad quality of DVB radio functionality. So, please start reporting the bugs so there is a change to fix those
