It sounds like your system may not be fast enough to encode two streams at
once?

There are two arguments to the FrameHeap configuration directive.  The 
first is the number of buffers that should be allocated, and that's the 
number you can try increasing.  The second (optional) argument is the size 
of the buffers in bytes, which will need to be increased only if you're 
using frames larger than 352x288.  -Nathan
