Hey, guys. I have had the problem of "No Disc" on a then new Sony Home theatre system from way back >20 years ago? It played all commercial CDs from big companies but refused all home created audio CDs including limited edition artist-produced CDs (examples being multiple CDs from small commercially produced runs (e.g. a say 100 or 200 CDs) some poetry by a group of poets in UK). I think it was an anti piracy measure - no industrial copyright protection - no play. I have not risked buying Sony since.
The system still works fine on big label CDs but I have to play my poetry recordings on another CD player.
