Plextor 708-a problem

hi everyone. i have a plextor 708-a dvdrw. i bought it like two months ago. i’ve been using it regularly. especially for backing up dvd movies. i had never had any problem with it, but since two weeks ago it can’t recognize normal cds, cdr or cdrw. it makes a weird sound and then it stops “thinking” . But when i tried with any dvd media, it works perfect. oh, also, i cant make copies of my already copied dvds. do u think this problem could have been caused by the last firmware i installed (1.7)? any solutions>?
i use memorex media.
thank you

Did it start right after you applied the update? Do you have another pc you can put it into to test? Try updating ide drivers?

after i installed the update it worked normal. no problems. a few days later, i couldnt use cd media.i do have another computer, ill try it there. updating ide drivers??

I have the same problem here…I installed version 1.08 of the firmware…

Only reading and writing of dvd(r/rw)'s works perfect…

I’m gonna ask plextor if this is a problem…
