Hp pavilion zv6000 wont recognize dvd+r
The answer is pretty simple, the ZV series is about 4 years old, back then DVD manufacturers decided which formats they would support as it was too expensive to make desktop drives, let alone, laptop drives that supported all formats. That drive only works with DVD-R and I believe DVD-RW. If you want to burn other formats, the laptop will only support them if you add an external drive of a newer make.
Note: Virtually all current models support ALL DVD formats and many support BluRay as well.
Hope this helps,
