I don't have a 4082B so I cannot help you directly. However, there are some things you can do to further investigate what is going on. First thing though, there are some things you need to know :
- The idea that you have to burn at really low speeds to get good burn quality is a myth. Most writers are made to burn discs at their rated speeds and generally burn at good quality at those speeds with good quality media.
The only time you may need to burn at 2x or 1x is if burning ps2/xbox disc images. However, this is not true for all of these devices. Some people have reported burning 16x discs at 16x for use with these devices and have had no problems.
- Ridisc does not manufacture its own media. It buys from various random disc manufacturers and rebrands. It is not particularly good quality media. If you are experiencing problems getting these discs to work with whatever device you are playing them on, try with some Verbatim/Taiyo Yuden discs instead.
Now then to get more information on what is going on, we need to find out what burn speeds A209 supports those discs at. To find out, use something like Nero CD Speed or DVD Identifier (http://dvdidentifier.cdfreaks.com, freeware) to find out the media ID of those discs.
Then get hold of MCSE (Media Code Speed Edit) from http://ala42.cdfreaks.com (also freeware). Use MCSE and load the A209 firmware. Check the media ID codes you retrieved above in the list of firmware strategies shown in MCSE. See what the supported burn speeds for these are shown as.
