I have noticed a potential bug in playing back radio channels.  The playback 
time of recorded radio channels is inflated by almost 40%.  This has been 
confirmed on four North American satellites on three different providers.  The 
reported time for a 10 minute recording will consistently appear as 13:47.  
Some have hypothesized the problem comes from the fact that vdr's timers are 
based on video frame rates, which of course don't exist on radio channels.

World Radio Network (wrn.org) is one example, and is broadcast on satellite 
worldwide, so perhaps this can be confirmed on other sats outside NA.  The 
timing problem makes it very difficult to skip commercials or "top of the hour" 
news reports or to skip between programming that occurs, for example, every 30 
minutes.  In America, I have made observations on Telstar5.  In Europe, you can 
try Sky Digital (Eurobird 1, 28.5E) or Eutelsat Hotbird 6 (13E) or Afristar 

Additionally, there appears to be a problem that some have reported with 
certain NA provider varying the video frame rate, causing *underreporting* of 
playback time, which would seem to confirm this hypothesis.
