Following that note - is it safe to say that for Model B we should be using gpu_mem_512=256 on a normal basis?
thanks for clarifying it

No, 128M is the recommended value. There are some circumstances where this isn't enough, so if you are having problems, then increasing this value is a useful test point.
If the problems go away, then we know your use case is using more than 128M of gpu_mem and can investigate further.

I have been at 256 forever, which was the stock setting in my config.txt file — never revised by me. What are the disadvantages of 256? I have checked available CPU memory from time to time and always found plenty of free RAM. What about a setting somewhere in between 128 and 256?

- All videos either from Nas or Streaming Services played as Audio and not Video
- When i got to setting in whatever option i tried to get into (Video, Audio , System etc.) the system freezes.

I got these problems with some of the builds too. Renaming or deleting the guisettings.xml fixed them for me. After that your gui is back to stock configuration so it might be a good idea renaming guisettings.xml to .bak i.e. to check if it helps. If this isn't the cause you can still rename it back.

If you rename it back and do a normal reboot from the interface, I think your guisettings.xml file will get overwritten (and lost). Doing a reboot from an ssh session avoids this.
