Last night I put a CD in the DVR and it came up but then froze when I hit play and now doesn't seem to want to read at all. It's trying to read but eventually defaults to an error - this cd won't work, try another (I hear the faint little click click click as it tries).

Is there a simple fix? Some sort of cleaning gizmo maybe?

Or

Should I buy another and if so any recommendations? I haven't used this one much but it is probably 5 or 6 years old and was fairly inexpensive to begin if I remember correctly.

TIA
