I too am having this issue. It is driving me crazy.
I dont think that it is network related. My DMA2100 is connected to a gigabit switch. I've tried changing the VMC box to 100/full, I have flow control enabled.
I have no issues on the VMC box watching/recording TV etc.
Very disappointed in the DMA2100, its constant crashing surely means that it is a product that shouldn't have been released yet. Hopefully a firmware update resolves the issue, and adds more codec support - god knows when that will happen.
