Dan: I have not had any problems with lyrics on factory disc. If you bought the cavs unit used, you might try a cd or dvd laser lense cleaner.
The things that I like about the 203 is the fact that you have about all of the controls on the machine and the built in reverb is pretty decent.
With the 105 unit, you pretty much have to use the remote control.
When I am doing a show with the karaoke, I do not use the mic connections on the front of the cavs unit, I use the connections on the mixer.
I also have a voco pro dual player, but for karaoke it has not held up near as well as the cavs units. Shortly after I purchased the voco pro, I lost the video on the left side player. I just wish that Cavs would come out with a dual player unit. If you have any questions give me a shout and I will do what I can to help you out.
Maybe some day my Friend Rick might develope a simply to use computer program for karaoke that is comparable to the RockIt Software!
