CD Extra query

Hi,

I’ve created a CD Extra, a mix of audio + data, using Nero 6.6.

I know that all the data’s on there (I checked it with Nero itself), but Windows Explorer only shows the audio track - I simply cannot access the data part of the disc.

I also know that my DVD drive (an LG GSA-4163B) supports this format, so am I missing something vital?

Mega-grateful for any insight.

Cheers!
