Keep in mind that SD cards have "class" ratings; the higher the number the faster
the write speed.
IIRC, you want class 10 or better for HD video; Class 6 *might* be okay for 2
channel 44.1K/24 bit audio.
Of course, the higher the class number, the more expensive the card.
And then there's the issue of a manufacturer fudging (or outright lying) about card
performance. (Gasp! Say it isn't so -- that a manu might fib just a little...)
Weird you got glitches though... I always figured the systems would be a little
more graceful and let you know you really shouldn't use your class 4 card for HD
video with 96K sound... But that could be wishful thinking on my part.
I'm sure others are well more versed in this; let us know any tips or tricks or
perhaps ways to verify write speeds...
