DVD Player shows "No Disc"

I'm not sure that I am posting for help in the right place, but I am
lost as to a solution. Perhaps someone will have an answer.

I have been burning my TV shows to disc using Vista DVD maker and they
have been playing in my Samsung HT-Q70 home theatre system with no
problems at all.

Last week, I realized that this particular unit plays DivX files, so I
converted all the files to DivX (12 episodes per disc as opposed to 3 or
4) and I put the disc in and it played. I was able to fast forward
through episodes with no problem.

I put another disc - regular DVD burnt using DVD Maker and it also
played with no problem.

I put the Divx Disc in and it wouldn't read it any more. Furthermore,
it won't play ANY of the DVD maker discs any more either. It'll play
retail DVDs with no problem, but NONE of the ones I burnt.

Why would it do so in the beginning and not recognize discs it played
before.

I have tried unplugging the unit from the wall overnight hoping
something would reset, but alas - no luck.

Anyone have a suggestion?

Thank you in advance.
