Nero shouldn't be the problem, and if you used to be able to play burnt CDs in there it shouldn't be the type of CD that is the problem (unless you are using CD-RWs now). Most likely you will need the CD player to be serviced because the laser might be a bit out of synch.
What brand of CD (eg Imation, TDK etc.) and what type (eg CD-R, CD-RW) are you trying to play?
Would you like to change your name to Homer Junior? People can call you Hoju.
Try some different brands of CD. Burn the CDs at the slowest speed you can, make sure there are gaps between the songs (my CD player doesnt like it too much when I reduce the gap to 0, has trouble finding tracks when I skip.
I would just buy an aftermarket HU. for around $300 you could be listening to MP3's. JVC have got some out around that price range. I know Pioneer start from about $450 onwards. Aftermarket HU's play burnt CD's heaps better, and they last longer than the crap that comes standard IMO. Imitation and TDK are the better brands to use, stay clear of silver tops and laser disc's though.
