I set up a couple of TV series to be recorded "every time" a few SVNs back. This worked fine until the current build.
The significant difference in my configuration is that I had to turn off the PSClient plugin because of errors on startup (discussed elsewhere). I usually exit MP (client) before putting my HTPC to sleep (hibernate) and count on TV Server to wake it up and make the recordings.
For the last two days, however, not recordings have been made. Even a one-time recording I set up wasn't made.
Is this feature broken in the current SVN?
Is it an undiagnosed bug that I should try to reproduce and document?
Or is it a side effect of the MP client being turned off?
I thought all of the recording was now handled by TV server, but since WebEPG still depends on MP (client), I'm not quite sure.

P.S. last night I put the HTPC to sleep with MP client running and the scheduled recording of a TV series worked.

P.P.S I now see that a later recording also took place on schedule even though the MP client wasn't running at hibernate / wake up time. Presumably the failed recordings were due to something else: maybe the HTPC was hung or completely off, when I thought it was hibernating.
