Anticipating the Buffalo version :wink:
Enjoy! :slight_smile:


Nice one, nice find!


Yeah I’ll wait for the buffalo version the Buffalo 1.50 works great for me I can wait. You know what they say all good things come to those who wait and taking your time ain’t laziness. :slight_smile:


THX for the info, but i will wait for the buffallo version.




Cool TY,seems the 109/A09 is all its ever gonna be.


yup. BTW what is multiborder recording with the first entry in the changelog.



Thanks for the heads-up.


same here, hopefully it wont be too long :slight_smile:


yeah, what does that do? and how do you use it?


Thanks, I have been waiting. Hopefully they improved the TY strat.


I haave burn TY and it was bad,prob with Leadout


I don’t have any problems with TY’s on this drive.


Updated and its perfectly good. Hopefully the MCC02RG20 performance will improve!


i mean TYG03
The problem is sometimes with TYG03 and MCC03RG20.


Marginal improvement burning TYG03 and MCC03RG20 with 1.55 firmware.

But 12x burning still faster than 16x burning. :confused:

And 16x burning very slow at ~ 6.40 mins.


Im 5m 30secs for 16x filling dvd +r to max limits.


is this including lead in and lead out times or closing track/finanlizing/synchronising cache?


Probably not. Pioneer has the same problem as NEC with this stuff. It skews either at the beginning (12X) or the end (8X). The only drive I have found that gave a flat scan was the LG 4163.


Seeing as though the NEC and Pioneer use the same chipset for their drives this doesn’t surprise me.
