I wouldn't say the hard disk or format was an issue, I record 3 HD
stream while watching another one from a WD Green drive and have no
issues at all.
Am wondering if the atom processor is a little under powered for what
your doing tho, or it's not being pushed up to max performance by the
governor and then basically the system is being strangled.
Can you ssh in and run top to see what your processor and memory usage is?
