I have also found this same problem with Stream The World's direct connect links to all the CBS Radio stations in mp3 format, while playing in XMPlay.http://provisioning.streamtheworld.com/pls/KLSXFM.pls
This is the direct stream address to KLSX/97.1 Free-FM/Los Angeles. This stream shows the same behavior as explained in the beginning of this thread. It's plays but it sounds too fast and just kicks out the audio too fast, buffers and lags out.
The service provider tells me not to use 3rd party applications but yet provides backdoor .pls links to different users.
