last I heard yavdr uses a bunch of patches but since I don't use it I don't know that 100%.
Well that's always good and cheap to talk about things about any individual heard about ... :-(
@Torgeir
Which version of yavdr do you use? Might it be possible to open a case on vdr-portal.de in yavdr sub-forum? English language is pretty much ok, at least I'm able to answer ... ;-)
