SOPC DMA in burst mode

I tried DMA (using the SOPC DMA) between two 64-bit SOPC memories. This works in 64-bit burst mode, but not when I use 32-bit DMA. I thought the burst adapters would solve this and translate the burs...

So the DMA controller is setup with a 32-bit width on it's avalon masters but the memories are 64-bit right? Yeah I would assume that the avalon fabric would take care of the width translation. I can't find anything in the documentation that would indicate addressing translation is not performed on burst transfers.
