[QUOTE=DrageMester;2002010][B][U]BenQ drives using the Nexperia chipset (e.g. DW1655/1650/1640/1620) have some strange scanning behaviour sometimes[/U][/B], so I use my BenQ DW1655 as a secondary scanning drive for DVDs, but I trust them less than LiteOn drives (and definitely les than Plextor drives, but they are too slow for everyday scanning of DVDs).
Strange behaviour for DVD scanning include:
- [B][U] Showing lots of POF but no actual reading problem
- Failing to read DVD but showing no POF and no out-of-spec PIE/PIF [/U][/B]
- Showing increases in jitter when other drives show decreases and vice versa*
- [B][U]Reported PIE/PIF dropping by orders of magnitude if a TRT is performed (even if done only briefly) before scanning[/U][/B] [/QUOTE]
Well, surprise! surprise!
Been here before.
The anomalies to which you refer (see bold underlined). Are not something I have ever experienced. Then found not to be present in Lite-On’s.
Other than Jitter* [B][U]being somewhat higher, consistantly[/U][/B].
This figure has been consistant for me & usually amounts to around 1% more.
As for the others.
They can & do appear in Lite-On’s too.
Which you prefer is entirely upto you.
If you stick with one.
As it’s all relative.
It doesn’t really matter.
i.e. Comparing one BenQ scan with another or Lite-On with Lite-On.
(Although we all know that this give a variation on a theme too.)
But how when comparing actually manufacturers, you can side on one as “being more accurate” is beyond me.
I prefer BenQ’s because they cover the spectrum more widely.
However it is immaterial as Lite-On have bought out & destroyed the competition.
BTW If it was chipset alone that produced the variations in results.
How come that other MediaTek chipset based drives from other manufacturers, can give similarly supposedly misleading scans?
Scanning is not pure science. (In domestic setups).
It is just a rough guide as to what maybe the disc quality of a particular burn.
So use it as such.
Or as I’ve already said “just for fun”.
