This turned out to be tricky. Writing to SDVOB on the primary vdc also writes to SDVOB on the aux vdc, but reading it back on the primary vdc always fails. Basically we never read from the primary vdc since we will end up trashing the aux vdc. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
