YouTube videos not capturing song titles then can't convert or burn to cd?

When I use replay media catcher on youtube many of the videos are not getting named automatically, they have letters/numbers then _videoplayback rather then the actual name.
I thought oh well no big deal I'll just rename them. They still played fine on the FLV player. But now I realize after finishing my collection over the last few weeks those ones that are not automatically named will not convert in replay converter to burn to cd. Whether I name them or leave them as is.
Those are the only ones I get an error on when trying to convert and burn cd's and I've tried the troubleshoot option each time but they still will not convert.
The only ones it will let me convert and burn to cd are the ones automatically named? I don't know if this would be considered a problem with replay media catcher (since they play in FLV player fine) Or replay converter since they won't convert.
What do I do to fix this?
Thank you
