Further to my last post, I applied the "vdr-2.3.1-fixcrashdelrec.diff" and "vdr-2.3.1-grantrecursivewritelocks-2.diff" that Klaus posted to the thread on vdr.portal.de :
http://www.vdr-portal.de/board1-news/board2-vdr-news/127271-announce-vdr-dev...
and I am no longer seg faulting.
I did not try this initially, as the poster "UFO", on that thread, for whom the patches were written, had not found any improvement.
Regards,
Richard
