Does anyone know if this is true, and if so are their any places where I can get drivers? Thanx, Chris Testa

DVD is not supported, per se. The good news is that a DVD-ROM drive (at least my SB Dxr2) is recognized as a plain IDE CD-ROM drive, so you can install from it, mount it, etc. You just can't use the DVD capabilities. -- Christopher J.

Does anyone know if this is true, and if so are : their any places where I can get drivers? When Red Hat says something is "not supported", this should be understood in context. It means that they haven't prepackaged support for the item in question to the extent of being able to stand behind it and offer technical assistance. Many things are possible with Linux that are not "Red Hat supported", and many pieces of hardware have drivers that are not so listed on Red Hat's supported hardware list. Please note that the above is _not_ intended as a slur against Red Hat Software. That's a perfectly sensible company policy. Support for DVD must be broken down into parts: 1. Recognising the drive as a valid SCSI or ATAPI device. Not a problem. 2. Recognising the filesystem. DVD drives can read CD-ROM disks. These are of course not a problem. The DVD media might be regular CD-style ISO9660 filesystems (not a problem), but are much more likely to use the DVD-specific "UDF" (universal disk format) fileystem, defined by the Optical Standards Technology Association as a subset of the ISO 13346 standard. See: http://www.osta.org/html/ostatech.html A Linux filesystem driver for UDF has been developed, and is available at http://trylinux.com/projects/udf/ See also http://www.bitwizard.nl/udf/ and http://www.rpi.edu/~veliaa/linux-dvd/ 3. Reading and playing MPEG (video) streams stored on the filesystem. This is problematic, and not yet supported, because of very heavy encryption used on such files. Please note that _all_ such files will be visible on UDF filesystems to the extent of seeing that there's a file there: Displaying it's another matter. -- Cheers, The cynics among us might say: "We laugh, Rick Moen monkeyboys -- Linux IS the mainstream UNIX now! rick (at) linuxmafia.com MuaHaHaHa!" but that would be rude. -- Jim Dennis
