This will be the most complete description of the problem, and if
this doesn't do it, then I have to call it quits.
1. The Set Up: Fedora Core 4, complete yum update as of minutes
before writing this email, latest kernel. Desktop PC, Pentium III,
600Mhz.
The output of lspci might help people understand the hardware specifics
that your computer has.
2. The Problem: When I put any kind of DVD, whether it's data or
video, into my DVD drives, they work poorly or not at all. Data CDs
and Audio CDs work fine, and I can even *write* DVDs on my external
DVD player and burn CDs on my other drives. It's only in reading DVDs
that the problem arrises.
External USB DVD drive: Will usually show the DVD icon on the
desktop, but copying data is extremely slow and will almost always
fail. I have succeeded maybe once or twice in copying data from a DVD
when the amount of data is less than 100 MB. But not reliably, and
not in any pattern that I can reproduce.
I haven't tried an external USB DVD burner yet. I will soon get one
where I could try out. Using an internal drive, I commonly transfer 2
gig files from the DVDs to a hard drive. Other than the one smp kernel
version killing the machine with defective DVDs, I had no problem
transferring files as large as 2 GB.
Internal DVD 1: Putting a DVD in this drive causes the light to flash
as if it is reading, but no icon comes up and it does not become
accessible. Ejection is impossible unless I reboot and press the
front eject button during the power on sequence, or if I force an
ejection by inserting a pin into the manual eject hole on the front
of the drive. This DVD drive is on the sequence of boot devices
(between floppy disk and before hard drive), so if there is a DVD
present in the time of booting, it will delay the boot process by
five to ten minutes and eventually show an error before booting.
This sounds more like a hardware settings issue. Do you have the jumpers
on the DVD drive set appropriately for master and slave operation? What
OS are you trying to boot with the 5 minute hang? I also had one Memorex
2x CDROM burner that loaded down the controller too much and failed at
times. Changing to another CD burner, which I still use corrected the
problem.
Internal DVD 2: Will spend about a minute reading the DVD before an
icon shows up on the desktop. Copying takes a long time (at least
twice the time it takes to copy the same number of files under
Windows XP), but it will actually complete. However, while it is
copying files, it seems to slow the whole system down, to the point
where mouse movement and typing is delayed.
I wouldn't be able to compare one to the other. I see no differences
between the two OS performance levels. I hardly use the XP OS on the
system though.
In Xine, when attempting to play a DVD, or an audio CD from my DVD
drive, I get the following error: There is no plugin available to
handle 'dvd:/'. Maybe MRC syntax is wrong or file/stream dource does
not exist.
Xine does not give me this error. I do get this error with totem though.
Where are you getting Xine from?
I hope someone will be able to figure out what the issue is and help
me get this resolved.

Here is the result of ls -l /dev/dvd:

It looks like the two internals are working in mdma2 mode and /dev/dvd2
is completely unknown by Linux.
Try searching for mdma2 and see what you come up with. I found the link
below that may show an earlier RH related thread you can sift through.
Good Luck!
