The thing about going by media brand name is that CD brands mean very little - most CD marketers (such as Sony) sub-contract their maufactures to a specialist in Asia. Common sub-contractees are CMC Magnetics, Ritek, Moser Baer India, sometimes Prodisc, and in very limited cases these days, Taiyo Yuden, Japan.

If so, you most likely have a tool installed called "Disc Speed" it could also be "CD DVD Speed" with an older version. You can use this tool to, among other things, identify the actual manufacturer of any recordable disc.
If you can find it, put one of your good discs into your optical drive, start the Disc/CD DVD Speed tool, select the drive from the list and click the "Disc Info" tab. The manufacturer will then be identified.
Then, to get discs that work in your stereo, it's a simple question of ensuring new discs are also made by the same manufacturer, there are plenty of online stores that sell ubranded and printable CDs by manufacturer, rather than by marketer.
