sorry for the delay.

I did look at the logs.
I also have some past experience where tvservice suddenly refuses to record anything.
and I mean anything, it doesnt have to be back2back or anything. I dont think this is related.
a tvservice restart fixes this.

it looks like the scheduler thread is locked down somewhere in a blocking call or some dead lock.
something that it never gets out of.

attaching a debugger while in this bad state would reveal where it is being blocked.
just hit debugger pause, and enter the "threads view" from within visual studio 20xx.
here you have an overview of all threads and where they currently are (stacktraces).
( just in case you are a dev )

next time, this happens, try and see if you can record anything at all.
just add some once recording, hitting the record button the remote control.

it happens pretty seldomly here.

the tvservice log should have this entry each time a recording is about to happen:
Scheduler: Time to record

like:

[QUOTE="gibman, post: 998711, member: 25430"] sorry for the delay. I did look at the logs.
