also you can discuss with a devellopers on xbmc-pvr irc channel on freenode.net
the archive you can find here is http://xbmc.newsforyou.com/xbmc-pvr
I have been using pvr-testing and pvr-testing2 for a while now, and try to keep up to date. However, I have two problems/questions which I want to either ask or flag to the developers but am unsure how to do it or even if it's a known issue?
I guess the best thing is to report these issues one by one on the XBMC bugtracker:
When you open new tickets, please use the prefix "pvr-testing:" when you report a bug regarding PVR stuff. Also choose the developer "alwinus" and the component "unified-pvr".
Additionally, if you also want more casual feedback on these reports from the German VDR community who is testing vnsiserver right now, please post links to your Trac tickets on http://www.vdr-portal.de/board/board.php?boardid=95. You can post there in English language, that's not a problem.
