Hello everybody ,
After doing some research of my own I made following conclusion's , have following findings
Hardware used :
-Plextor PX-712 with latest Official 1.05 Firmware with Plextoos Pro 2.17 for Pi/PO scans
-NEC 3500 AG with latest Beta 2.19 Firmware for burning , all DVD's have been created using the nero Writespeedtestimage
First of al CMC Magnetics 8 x DVD-R (media I have used for a long time)
This media on the NEC writer without a doubt idle media
TDK 8x DVD+R TDK002
Fujifilm Taio Yuden 8x DVD+R YUDEN000T02
All of previous were burned @ original speed (8x) , but with the altered firmware my NEC burns the TDK and the TY as known @ 16 x also
TDK002 8x rated @ 16x
YUDEN000T02 8x rated @ 16x
Now the tabels turn in as @ 8x the Yuden looks better then the TDK but now it's reverse
My Questions to all Obviously if I didn't have the NEC 16x burner I would stay with The CMC Magnetics media alltough it's hard to come by
My goal is to burns from now on @ high speed (16x)
The Yuden and the Tdk are the only media i could find that i could write @ 16x (the verbatim MCC004 also but it's to pricy , more the double of the Yuden or TDK or CMC)
But write Quality is verry important to me personal , having had many DVD in the past and still now come out of my storagebox and are not readable anymore(IO error ....)partially or completely , also with the CMC i'm using now , I want the best quality burn available in order to not lose most of the times important data wich I can't or hardly afterwards can replace.
-So , what should I do , stay with my DVD-R burning @ 8x (so slow now

) ?
-Or should I go to the DVD+R TDK or DVD+R Fujifilm (Taoi Yuden) wich burn at 16x ?
-The scans @ 16x of the TY and the TDK , are them quality burns on a scale of ??/10 ?
-Wich 1 of the 2 to chose for future purschases ? (near future cuz i'm almost out)
-Are PI AND PO errors important for the Burnquality or mostly only PI ?
-What are the how must I define , limits of PI and PO for a perfect superdeluxe quality burn ?
Hope I can get some feedback on my Questions and maybe have helped others with the scans and analysation of my findings
