Old Bose 321 dvd player will not play home burnt movies

Hi i have a old Bose 321 dvd player that up to about a little while ago would play my home burnt movies but now it just says bad disk but these disks will play in my computer and on my PS2

 

If you've changed your blank media brand that could be a likely reason for your new problems. Try Taiyo Yuden or Verbatim branded media. Burn no faster than 8x or 6x on 16x discs.

 

I agree with Peshtigo. Just wondering Carbira1, what brand are you using now? and did you just change brands? and if you did, what were you using?

*EDIT*
Also, -R,+R, RW's make a difference too. I believe the -R plays better in most DVD players. Someone can correct me if I am wrong.

 

+R's booktyped to DVD-ROM plays best of all.
After that, I believe it is -R

 

I have been using the same brand Memorex DVD+RWS I have also checked for scrashes and tried multiple burns on multiple dvds

 

I don't know. I've been using Verbatim plus R discs for years. Nine times out of ten I forget to change the book type and they play on all machines they're tried on anyway. Must be why I don't think about it. I use Imgburn and I know I can change the settings, I just haven't yet.

 

Lots of older players have trouble with the cheaper 16x disks.. regardless of brand or dye. Some just don't like 16x disks full stop.
It's getting hard to find 8x disks which is why I kept a stash of 5000 cheap samsung (optodisk and fine for general use) for people I know have old players.

 

Mine are 4X

 

also i have a new problem, I tried to put the system update disk in and it updated (so i think) but i can not get the system disk out it just sits there with the backlight on and that is all that it will do. I can not get it to turn on or get the update disk out.
