DVDRW 1116IM freezes MS Explorer

I bought a DVDRW over the internet and installed it myself into my Dell Dimension 2400. It came with a Nero disk, but no drivers. After installing, I was able to read 1 commercially produced DVD (movie), but any other DVD that I load into it causes MS Explorer to freeze.

I downloaded a driver and “upgraded”, but still get the same results.

The drive will read CD’s just fine without freezing Explorer.

Does this sound like a decoder problem? If so, where do I get the proper decoder?

Thanks.
