Transcode 360 choppy playback - stutters and pauses

I recently went watch a movie on my xbox 360 using MyMovies and Watch Stream, which utilizes Transcode 360 to encode the movie. The movie kept pausing and stuttering. It was not a CPU issue. I stopped the transcode service on the Media Center (a reboot of the machine will accomplish the same, getting it to stop transcoding), opened the Transcode 360 Configuration Utility and on the left click on Advanced. On the right, at the bottom I checkmarked 'Downmix multi-channel AC3 to stereo MPEG audio' (I had it unchecked from some previous testing I was doing). I then started the Transcode 360 service (if you rebooted you don't need to do this). I then tried that same movie and it played very nicely. No stuttering or pausing.

Using Symantec Endpoint Protection in Safe Mode - Dealing with service not running error

Sometimes it is necessary to do an Antivirus scan while in safemode. I have noticed an issue with Symantec Endpoint Protection. After booting into safemode and attempting to launch Symantec Endpoint Protection, an error appears which says "It appears that the Symantec Management Client service is not running. You will not be able to manage network protection settings through the main user interface until it is running. Do you want to start the service now?"

It seems you would want to say Yes, but that will not work. You must choose No. Then the user interface will load and you can scan. You may receive a notice about realtime protection being disabled. For this purpose, that can be ignored.
