Hmm, the download doesn’t work here either and it’s also not available on the Japanese website anymore as far as I can see.
I hope they release one soon, not that it is already necessary cause my 750 works fine (for the moment 
) I also bought Nero 7, no problems with it (for the moment )
it is 7.0.0.0 :), I hope they release an update like they did for Nero 6

Nero 7.0.0.0 is crap get 7.0.1.2 sharpish! My PX-750A is crap 
all this time waiting to afford one and it sucks cock! (And not mine) sorry but the DVD-RAM just don’t work! gonna send it back unless Plextor europe can work a miracle (I’v heard it’s just a re-badged example anyway it works on DVD-R and DVD+R (Altohugh Nero 7.0.1.2 dropped the writing speed on a cheap 8x to 4x (prob crap media) THe DVD-RAM that the "plextor 750-a CAN’T handle is a panasonic LM-HB47E
I have tried this and didn’t work thanks for the hack though, sure to help someone!
I got it to work now (not sure how i feel!) okay i…
Went to system/hardware and updated the drive for the .inf file in one of the panasonic etc drive packs
then (after restart) the drive didn’t work so i uninstalled from windows.
windows did not restart proplery but after hard reset windows loaded again with a new Drive (DVD-RAM!!!) what a bover! Sorry My soloution is vague it was an accident!
Seems that Plextor need a DVD-RAM Driver in the box or on-line. Do you agree?
Yes me too. I was dissapointed that they even couldn’t help me when I mailed them. They just said that I had to try all availlable dvd-ram drivers.
But I got the DVD-ramdriver to work with my PX-750. I used the driver from
a link somewhere else in this forum

links of the files are:

http://upload.cdfreaks.com/rdgrimes/dvdram_xp_5021.exe
I changed the following things in the installation:
DVDRamType.ini
Under the head [SearchString]
Add PX-750A to the empty 003=
dvdram.inf
search for the strings:
TEAC_DV-W516E_devdesc = "TEAC DV-W516E"
TEAC_DV-W516E_1_devdesc = "TEAC DV-W516E"
TEAC_DV-W516E_4_devdesc = "TEAC DV-W516E"
TEAC_DV-W516E_S_devdesc = “TEAC DV-W516E”
and change them to:
TEAC_DV-W516E_devdesc = "PLEXTOR DVDR PX-750A"
TEAC_DV-W516E_1_devdesc = "PLEXTOR DVDR PX-750A"
TEAC_DV-W516E_4_devdesc = "PLEXTOR DVDR PX-750A"
TEAC_DV-W516E_S_devdesc = “PLEXTOR DVDR PX-750A”
Note: these strings occur 2 times in the file and there are 2 spaces between
DVDR and PX-750A
After changing those 2 files just install the driver with setup.exe. After the reboot an extra icon of a removable drive should appear in My Computer
