I just downloaded RealPlayer10Gold from the real website and installed it (removing helix player and getting that libstd++ thing). The installation was successful. However, whenever I play any real media files, it has sound but no video.
I thought it's some sort of codec conflict. So I removed MPlayer, but it didn't help.
Now I don't know what to do - all the real player help online was about how to get that libstd library and how to remove Helix player. Nothing talked about playback with sound but no video.
