Test Idea:

have you tried this with any alternate real  codecs? 

above you use by default for audio: rasipr  and video: ffrv20

choice list generated from mplayer -vc help | grep rv20

rv20        realvid   working   Linux RealPlayer 8 RV20 decoder  [drv2.so.6.0]
rv20win     realvid   working   Win32 RealPlayer 8 RV20 decoder  [drv23260.dll]
rv20mac     realvid   working   Mac OS X RealPlayer 9 RV20 decoder  
[drv2.bundle/Contents/MacOS/drv2]
ffrv20      ffmpeg    untested  FFmpeg RV20 decoder  [rv20]

 mplayer -ac help | grep sipr

rasipr      realaud   working   RealAudio Sipro  [sipr.so.6.0]
rasiprwin   realaud   working   Win32 RealAudio Sipro  [sipr3260.dll]
rasiprmac   realaud   working   Mac OS X RealAudio Sipro  
[sipr.bundle/Contents/MacOS/sipr]

for example if you can use the win32 codecs
try 
mplayer -vc rv20win -ac rasiprwin MG01_Good Night.rm
