Not exactly, 'A'vailable means that the buffer is available for
decoding onto. So if the CPU usage were high I'd suspect the 
decoder wasn't keeping up. But since the it isn't, I'd look at
the RingBuffer next. I just wanted to let you know it probably
isn't something like the audio playback, video display , or A/V
sync causing the problem.

It probably isn't a CPU bound problem, but rather something like a
buffer size, or long timeout problem.

Yeah it would be nice.
