Query: terapin TX-0002 -- trouble using non-terapin CD-R

I have owned one of these things since 2004. It works fine if you use "terapin brand" CD-R's. I have not found an alternate brand that the machine will recognize, so I use the one terapin brand CD-RW that came with the machine. If I lose that CD-RW the machine is useless. I would not recommend its purchase.
