The write speed graph looks like a Nec (Optiarc).
The verify (read) speed is never above 6x. Seems to be an issue. Sure it's on 'MAX'?
Never had/or have Daemon Tools installed?
It's a LG GSA-H55L firmware latest v1.06.
Never had Daemon Tools....of course have alot of item loaded on this PC, codecs, including CCCP, Pinnacle, etc. for audio & video editing.
Overall it seems fast enough for me...it's an 3Gh Intel P4 with XP SP3 with 4GB RAM...I walk away at Burn and Verify and come back.
I'm willing to trade-off a little longer cycle tiem for more reliable burn.
I use Verbatim DL Singapore only DVD+R and for SL Verbatim DVD-R....haven't found Singapore made but Taiwan seems OK.
