You are correct for DVD-RW and with all DVD- formats, there are frequent round |
| 14 |
robin tests with all writers vs. allr readers and all media. This kind of test |
| 15 |
does not exist for DVD+RW and I've seen a lot of problems with media |
| 16 |
interchange. |

Just a note: |
| 32 |
|
| 33 |
When I got my first DVD writer in February 1998, the price of the writer |
| 34 |
was 15000 US$ and the price of a media was 80 US$. |
| 35 |
|
| 36 |
When I received my first BR writer, the price of the writer was 600 Euro and |
| 37 |
the price of a medium was ~ 20 Euro. |
| 38 |
|
| 39 |
Now the price for a medium is 1.5...3 Euro and the price for a writer is |
| 40 |
60...200 Euro. It took 5 years for DVD to get into this price level and it took |
| 41 |
5 years for BR to get into this price level. So where do you see a difference? |
| 42 |
|
| 43 |
There is another difference: the fact that flash memory has become cheap did |
| 44 |
change the interest of the people. |
