Weird DVD-ROM malfunctoin??!??

[gooberguy]

My DVD-ROM, that came in a sony rx-450 is somewhat malfunctioning. The DVD-ROM was able to play anything, a cou ple months ago. Now all it plays is normal Cd's and a select few dvds? What is the problem? THis is the "data" that i collected.

Sony DVD-ROM

(all dvds play fine in standalone dvd
and are all ntsc region 1 unless stated.)


Played

Dragonball Z dvd - Region 1,2,4 )bought in USA store.
Comp-USA DVD-R 4.7 GB - with video on it
Any normal cd. (blank, cd-rom, music cd,vcd whatever)



DID NOT play

blockbuster rented big fish
i-spy
spiderman
hulk
star wars II
stuck on you
the bourne identity
X2

it seems like the dvd rom will NOW only play non-official dvds. (all the dvds listed above are official release movies, exept that one comp usa dvd with home footage on it.)

anybody have any suggestions?

I suggest updating the firmware for the drive. It actually sounds to me like you have a hardware or driver problem, but the firmware is a good place to start.

[tekkieman]

Tried cleaning the drive?

[gooberguy]

Cleaning? as in a cd lens cleaner thingie. (the thing similar to a vhs head cleaner?)

i dont know what firmware is maybe you can further explain?

THanks a bunch!

Go to the manufacturers website.

Look in the downloads section

There might be a firmware driver update for your drive.

[Doramius]

Firmware is "like" a software (and I use this term very loosely) for an IC chip. It can be flashed for an update, but needs to be done properly, or the devices can become an expensive paperweight. because it's a permanent change (I think of FIRM as in solid) it's FIRMware. That's the best description I can give you, though someone might have a better or more accurate way of explaining it.

OK, i got an updated firmware but, i need to acsess a MS DOS in win xp pro. is there any other msdos then comand prompt in acsessories in start menu?

BEcause: The instructions iunstruct me to


""Firmware update command
Type the following and press the ENTER key at the end:

UPG5A /n G6TAxxx.HEX

-/n will vary depending on which IDE bus the target DVD-ROM drive is
configured for. Type one of the following, depending on which IDE bus
(Primary/Secondary) and setting(Master/Slave)the target DVD-ROM drive
is configured:
n=1: Primary Slave
n=2: Secondary Master
n=3: Secondary Slave""


And when i do that i get errors, so i thought it might be somthing else then command prompt.

Once again thanks for the help!

EDIT: just in case, my dvd is a pioneer dvd-116R

bump ~~ sry, but i still need help please

[Ripper2860]

What errors do you get?

[stiltman]

I'm not a big fan of firmware update unless you have a specific reason for doing so. In your case I wouldn't. I wouldjust try cleaning it

[gooberguy]

OK,

when i put in UPG5A /2 rpc1122.HEX
(2 for secoundary master)
i get CD-ROM IS NOT PRESENT

the drive is present, i dont know why the program is not detecting it.
