cds don't read properly

hey this is a very weird problem..
my friend gave me a couple of cds with .avi files in them and for some reason my computer is only reading them as 63.3mb each
they're not 63.3mb they're 500+
i'm using redhat 7.3 kde 3
does anyone know what could be causing this?

Tell me what kind of computer your friend has? How did he/she format the cds, ask them? If he/she has a MAC, that might be your answer. Did he/she format them ISO or something other.
Did they 'finalize' the cd's, or leave them open for more writing. If they came from any computer on a college campus, no one knows what might be wrong with the discs (that's a joke).
But really, find out about 'how' they were 'authored', and that should tell you and us the answer. I'll assume all your other Cd's read the correct amount of MB's.

well he uses windows xp pro and i would assume nero as i gave him a copy of it but i didn't ask whether he finalized the cds or not they work fine on the windows box i have and they work fine on other windows computers i had to copy them from cd to my windows box and then send them through irc in order to get them on this computer
and he didn't use an .iso just burned the .avi files straight i don't even think he knows what an iso is heh

and oh ya .. my drives do read all the other cds i've used as full cds
its just the .avi cds he gives me that show up as 63.3mb :/

do the avi's play??
If they played I'd not worry to much how they show up :-)

they do play but only 63.3mb worth
which equals out to like 10 minutes and the full .avi should be close to two hours.....

You said they work fine on the windows box, can play all two hours worth of avi's. So it's safe to assume that the 'files exist'.
Let's take this a step at a time.
1. When the cd is mounted and you use a file manager, what does it say about the disk, file sizes etc?
2. Unmount the cdrom.
3. What is your mount command for your cdrom, (see your /etc/fstab file), it could be possible you are mounting the disk via 'dos', when it should be vfat, or ntfs, maybe 'auto' is not working right.
Try
mount -t ntfs /dev/XXXX /mnt/where-ever-you-mount
usually
mount -t ntfs /dev/hdc /mnt/cdrom
or
mount -t vfat /dev/hdc /mnt/cdrom

After that, you should be able to see the 'whole' file and play your avi's.
3. That's my best guess!
