I save all my MCE recorded TV to a share on WHS named Recorded TV.  The recorded content is moved there after MCE finishes recording on it's local disk by an WHS add-in application called TV Manager.  This program just moves the dvr-ms file to the share when recording is finished.  I installed DVRMSoolbox 1.0.0.8 on the WHS machine and told FileWatcher to watch the D:\shares\Recorded TV and kick off the commercial scan when a new recording appears.  The commercial file is output to a subdirectory of the WHS Recorded TV folder called Commercials.  This way any MCE machine in the house can watch the program and knows where to find the commercials file.

 However the FileWatcher service doesn't appear to react to any new recording as they are copied in by TV Manager.  I can use the GUI to manually cause the commercial scan to occur and it completes fine.  I've checked and the the FileWatcher service is running (Automatic Start), but still no luck.  The DVRMSFileWatcher.log just has the following entries in it:  Anyone have any ideas?

 what happens if you copy the file over manually?

Nothing happened either if I manually copied over the files, but I got FileWatcher to work by checking the "Allow service to interact with with desktop" box on the Log On tab on the DVRMSFileWatcherService Properties box.  Now FileWatcher kicks off the commercial detection everytime but I'm having a different problem.

The only thing I'm using the toolbox for right now is to detect commercials in the HD over the air programs I record.  I've setup the processing conditions on nativecommdetect to only use ShowAnalyzer and everything works fine everytime if I kick it off from the GUI.  However if FIleWatcher kicks off the commercial scan most often the scan fails.  This happens whether TV Manager copies the file over or I manually copy the file over.

Below is a job listing where the FileWatcher worked:

However most frequently the commercial scan with FileWatcher doesn't work.  I noticed in the job log that it looks like nativecommdetect tried to use comskip instead of ShowAnalyzer and that running comskip with the run command must have some permissions problem.

Here is the jobs log on one that failed:

I thought maybe the wait time in FileWatcher was too short (it was 5 minutes), because it takes a lot longer for TV Manager to copy the program over the network than it does for the MCE PC to copy it from TempRec to Recorded TV on the same machine.  I kicked the wait parameter up to 30 minutes but that still has not solved the problem.  At this point I'm out of ideas and could use some help.

It doesn't seem to make any difference.  I changed the service so that it starts under the administrator account.
