I have seen the same thing; not recently, but that's probably because 
nothing has been scheduled recently for end-of-service times. Since I 
run virtually all my recordings through mythcutprojectx I just did that 
- with no cutlist - and AFAIR they then played fine and could be edited 
as normal.  It's certainly inconvenient, and that workaround would 
probably not improve the WAF: I'm not sure it's a bug.

I also used to have difficulties when a recording started before 
start-of-service -  BBC THREE and BBC FOUR both starting at 7pm - but
recently that doesn't seem to have been a problem either.
