I did try the rpm -e method and the yum remove method. I was missing the block letters in helixplayer (the H and P) and was making a small mistake in the spelling of rhythmbox. I corrected the spelling and sucessfully unistalled both.
As for real player the files had been overwritten by a helixplayer upgrade. Now everythings fine.
Thank you very much.
Really appreciate it.
