Nah... I already tried this... no help what so ever... same sluggish 5 minute loading time...
Funny that this only happens on 3.x versions, when 2.x and even beta 4.x are working fine... It's just frustrating...
I have the same issue, only difference is, since it's rather large m3u list (about 50k programs), it takes around five minutes OR MORE to load it. And it is not only related to windows, same happens on my MacBook so for sure it is not related to the graphic card driver as suggested above. On Windows...
