What is the CPU type and speed you are using?  In my experience, data
rates above about 500 kbps are difficult to receive on a typical
laptop platform due to lack of sufficient CPU cycles.  On an Intel
Core2 Duo at 2.1 GHz (IBM Thinkpad T60), I can't go above 800 kbps.
Your rate of 2 Mbps is likely much too high. Are you seeing any "uO"
on your output?
