* 56ebbc6 introduced logic in place for playback conditions on the Amlogic
  devices. However, after this commit was merged MPEG2 streams started to
  be HW decoded and thus throwing off the logic put in place to accomodate

SlingboxLib: Fix alternative CSlingbox constructor

CSlingbox::CSlingbox(const char * szAddress, unsigned int uiPort /* = 5001 */) {
