Answer: Some computers output less power than others through the USB ports. On some PCs, one USB cable is enough, but to be safe and to avoid write errors, connecting both USB cables is highly recommended.
Answer: There is a lever on the bottom of the drive. Moving the lever back will cause the cover to open even when there is no power applied to the drive.
Answer: The DVR-XD10 may work with other software in a Windows 7, Vista, or XP SP3 environment. In a limited way, it will even work with Mac OS X software.
Answer: Although Pioneer does not guarantee operation with Mac OS X, being that the drive is connected through USB, the drive can operate in a Mac OS X environment (tested with Mac OS X 10.6.7). The drive should be able to read and write to DVD, and CD media but it depends on the Mac OS software (finder/disc utility/etc). Video playback also depends on the Mac OS software. Note that the bundled Nero software does not work in the Mac OS X environment. Read and write performance will not be the same in a Mac OS X environment.
Answer: No, the drive should only be used in a horizontal (lying down) orientation.
Answer: If the USB hub is powered (AC adapter), the DVR-XD10 may work, however the drive’s read and write speed may be reduced. The DVR-XD10 will not work if the USB hub is not powered.
