- Why do I get poor audio quality from recorded CDs?
Noise can be introduced into audio tracks during direct audio extraction from the source CD-ROM drive due to a phenomena called "jitter". Newer types of CD-ROM drive are capable of Jitter Correction which removes this noise. All Diamond Data CD-ROM drives with maximum speeds of 24X or greater have this feature.
To test audio tracks before recording them, try extracting the tracks to a WAV file on the hard drive and playing them using the Media Player to check the sound quality before you copy them to CD.
- Why is the quality poor when video files are played?
Poor video quality can be caused by the same situations that cause buffer underrun (refer to questions 1 and 2 of the section dealing with recording problems).
This can also happen if video card is slow - reduce the size of video window and close all other running applications. An upgrade your video card or the system's CPU may be the only solution in some circumstances.
- Why am I experiencing problems reading a recorded disc in my CD-ROM drive?
CD-RW discs can only be used in a CD-Rewriter or a MultiRead compliant CD-ROM drive. Diamond Data CD-ROM drives with speeds of 32X or higher are MultiRead compliant, as is the model 624A-323 24X drive.
Try ejecting the CD and re-loading it. Refresh the screen by selecting the "My Computer" icon in Windows Explorer and pressing the F5 key.
Check the disc specifications. All discs have a maximum recording speed. Make sure that the speed of the recorder during writing was equal to or less than the specified maximum speed.
Discs that have been created with Nero's InCD program use the UDF format. A MultiRead compliant CD-ROM drive and UDF reader software must be installed on the PC before this type of CD can be read.
Nero's UDF reader software is available for free download at their web site:
Also check whether the CD Recorder or other CD-ROM drives can read the CD disc properly. If so, then the problem is probably with the CD-ROM drive.
- Can I use hard drive compression software?
The use of hard drive compression software is not recommended when a CD recorder is installed. CD-R and CD-RW writing programs may check free space to estimate required space. However, due to variances in the compression software's compression ratio with different types of data files, the actual space available may vary and may not be enough for disc copying even though the space reported as being available by the operating system seems to be sufficient.
- How can I maintain optimal writing performance?
Regularly run disc de-fragmentation and scanning programs on your hard drive(s). Please refer to your Windows manual for instructions. Doing this improves the average file access time of the hard drive resulting in more stable transfer of data to the recorder from the hard disk drive.
- Why do I get an audible gap between tracks on disk at once (continuous) audio CDs when playing back through some applications (e.g., Winamp or Windows media player)?
Some media playing (namely those with visualisation capabilities) applications play audio CDs via DAE (Digital Audio Extraction) rather than through the standard audio playback facility. To resolve this use the standard Windows CD Audio player (under programs => accessories => entertainment).
