I've started work on this problem yesterday. I discovered that the MPEG
data is placed at the correct memory location so the shift happens either
in the DMA handling (most likely) or in the internal buffer handling of
the driver. I can easily reproduce it, so that helps a lot. I hope I can
find the cause quickly. I have several ideas, but it needs more debugging
and tracing.
