dvd module will read CD's but not DVD's
i have a Pismo and switched out the DVD-ROM/CD-ROM Module with one i bought, barely used and said to be in good condition, off Amazon.com. When i first tried to use the new used one, it barely made a sound and did not load a movie. i played around with some settings and it began reading DVD's [accompanied with the expected long whirling sound]. i watched 1 movie and then part of another. The second one started going on the blip so i had to force quit DVD Player [the software that i use and which i can still get to open through application]. Now the wouldn't read any DVD [e.g. the DVD movie icon does not pop up on the desktop. But it does read CD and i can listen to music.
Why would the module [drive?] read a CD and not a DVD?
am i having a software problem, setting problem, or hardware [module/optical laser?] problem>
any suggestions as to what i can do to get the dvd module to read a movie.
My System Profiler shows that a "LG DVD-ROM DRN-80808" is connected in my ATA device tree. It shows that the Drive is CD-ROM/DVD-ROM. The protocol is ATAPI and that it has "Removable Disk"
i tried using a CD optical drive cleaning disk even though it has been able to recognize a CD, just not a DVD. Doing so didn't help.
i have tried numerous movie DVD's, hoping for a miracle. those that were recognized before are no longer recognized. i tried two DVD's that were home-made [using blank DVD's] but they did not work either.
i don't have any data DVD's but i will most assuredly try one once i get my hands on one.
i am sorta flustered because the optical laser can recognize a CD but not a DVD. Why would this happen? i would think if it didn't recognize one, it would not recognize the other. [when i put in a CD, it opens up quicktime player, but it is supposed to open up DVD player when i insert a DVD].
Also for a few days, it recognized movie DVD's but then it stopped doing so. i find it amazing that it would tease me as working but then just stopped working - after only 1 and 2/3 movie. it seems as if i did something to get it to work but then when i had to force quit dvd player, it just stopped working.
i bought it from a private party through amazon, one who sells other products such as books, VHS movies, movie DVD's through Amazon but normally not computer parts. this drive is from a powerbook that went south on her. she doesn't have another to swap out. i also am thinking of keeping it for the CD player works and i don't want to put the old one [the one i swapped out] back in as it played neither CD nor DVD's and the outer door was becoming detached [also bad feng shui (sic)]
i thank you both - rdkline and machead3 for your imput.
machead3, i didn't mean to answer my own question. i just didn't know how to add additional information or make a comment as i am totally new to this website and i STILL don't see where i click to make a comment or add information. i have reviewed this entire page and still don't know how to do anything but answer.
i also see a thick line through my "answer" which obscures some of the text. i don't now where that line came from, why it appears, nor how to remove it. i am as flustered by this website as i am by my DVD drive.
Is this a good question?
