Well a good place to start is own a BenQ & then, to read this forum.
**** I am doing my research ahead of time. I will soon have a BENQ 1620 come Christmas. I actually chose the 1620 over the PIO 108 after tremendous hours of research.
"Very important," learn how to do a "search" in this forum.
**** know how to do that, thanks
There is a lot of knowledge imparted here. You may discover that B7K9 has a faster write speed than B7P9 for certain media, but quality on the media you wish to use?
***** I am aware of this as well.
New firmwares are being released by BenQ almost monthly. Each release has it's plus & minus aspects, better quality, slower writing, more capability on more media, faster burning speed, etc. Couple that with each burner responding within specs, yet slightly differently to the same firmware, and you can see you have your own quest of the Holy Grail lying before you. This is assuming that your basic computer system is in order, your software does not conflict & your drive functions properly. You can get help with those issues here too.
But to directly answer your questions,
1) When upgrading firmware, I would try the IO Magic G7Z9 firmware 1st.
***** Really, I thought most jump to B7P9?
With this caveat. Make sure your BenQ is functioning correctly from the start. Burn some discs with your existing software This is for warranty & to eliminate confusion with OS or software problems.
***** What do you mean this is for warranty? I see that you can cross flash from G to B and back again. Please clarify.
Debug system conflicts before you upgrade your firmware.
2) see this thread as a starting point for changing your firmware from G to B or??
***** Thanks, I have seen this previously.
3) B7P9 seems to be currently the most popular firmware used for internal drives.
**** That is what I will have an internal BENQ1620.
4) As for differences between the firmware releases, there are change logs, on each firmware released by BenQ, Just go to their Official site to read them. Just click on the Pencil icon.
***** Thanks, I did not know this. There are just so many things to keep track of with these units.
