DVD-RW
ReWritable media:
In these DVD-RW tests, the FujiFilm and Memorex have been rewritten to several times prior to this review, with none been rewritten to more than 10 times. Unlike other disc formats, DVD-RW discs can be quick or full initialised. For this review, all of our DVD-RW's are quick initialised and the initialise times given include the recognition time from the moment the tray is loaded and the time it takes to initialise the disc.
For the DVD-RW read-speed graphs, we were unable to use the BenQ drive as it keeps randomly stopping while doing a read-speed scan on most of the DVD-RW's written by our review drive; reporting CRC errors as shown below. We even attempted to update the firmware to 'BCDC", BenQ's latest at this time of writing, but without any improvement. Even a basic reading of the 'VIDEO_TS' folder returns CRC errors midway through. So, in order to test our DVD-RW recordings, we used a Lite-On 1693s for these read-speed graphs. As a result, we can only test for a maximum read-speed of up to 8x, unlike with the DVD+RW discs where we were able to perform read-speed graphs of up to 12x in the BenQ drive:

Summary:
This DVD recorder seems to provide good results for our DVD+R media with several excellent results also. Like a few DVD+R disc tests, a few DVD-R discs had PIF spikes in excess of 4, however all of the DVD-R media played without any issue in all of our equipment. When it comes to DVD-RW, this DVD recorder seems to do a far better job compared with DVD+RW media with results rivalling write-once media in a few cases. All but one disc stayed fully within the PI and PIF guidelines for good quality media. Unfortunately, only two of the DVD-RW's would play properly in our BenQ DW1650 DVD writer, however as all of the DVD-R and DVD-RW discs gave no playback issues in all the rest of our players, this seems to be an issue with the BenQ itself rather than the DVD-RW media or the review drive's recording method.






I don´t understand the following text in this review about the Lite-On LVW-1105HC:
http://www.cdfreaks.com/article/263/11
Positive:
Excellent DVD+R, DVD-R and DVD-RW recording quality.
Negative:
Disappointing recorded picture quality with both HQ and SP modes.
What do these words mean:
recording quality
and what does these words means:
recorded picture quality
or is the meaning of them the same?
If both words have the same meaning, then there ist the decent recording quality.
In the review stand this:
Decent recording quality in its long play modes.
Allthough, isn´t that Long Play Modus is always not so good as short play or HQ modus?
Why is the record quality from the long play modus in this Lite-On LVW-1105HC even better then the record quality in the HQ or SP modus?
