I decided on taiyo yuden watershield dvd-r 16x (TYG03) as my primary distribution media for home made dvd.
Using nero cd/dvd speed to scan, I noticed the PI error rate usually starts off high, then gets lower towards the center of the scan, then gets higher again near the edge. Is there anything I can do to reduce the starting and ending PI errors?
If something did not burn well, it usually happens near the end. I tried burning at different speed and 8x seems to be the best using a pioneer DVR212D (firmware 1.22).
Perhaps there is some burning software that varies the burning speed depending on the position of the track to improve reliability?
Would be even better if the burning software can test different burning strategy on a sacrifice disk to determine the best burning strategy.
