This media is made by prodisc and works very bad in most writers.
memorex dual-x dvd-writer: writing at 16X makes unreadable discs
Lite-on LTR-52246S and LTC-48161H: works, but very high C1 error count.
Optorite CW-5205: works but very high C1 and C2 error count.
AOpen CRW5224: works but high C1 and C2 error count.
plextor premium: works with powerec enabled since writespeed drops to 24X, still a few C2 errors and a lot of C1 errors.
Samsung SM-352B: same as the others: a lot of C1 and C2 errors.
Try to get ritek or taiyo yuden as these seems to be quite good.
