Large PipedInputStreams cause severe slowdowns and high memory usage #2

Using a PipedInputStream as the source results in TivoLibre running progressively slower and consuming more memory as the decode progresses. Regular InputStreams do not exhibit this behavior.

Resolved by removing the ConcurrentByteBuffer.
