CD/DVD and sound issues

Ok, I've been cruising around in the forums here for a while. I found some interesting answers to questions I've had, gave a few pieces of advice to people (hopefully they've worked their way out of their problems). The site is a nice effort to make linux more approachable.
However, my two main problems remain:
First of all, here's my h/w:
AMD Athlon 1300 MHz on a MK35V m/b
256Mb RAM (not that it matters)
ATi Radeon 9100 (recognised as 9100 QM)
Samsung SyncMaster 151s 15'' TFT (recognised as 150s)
JMLS DVD-ROM LTD-166S (slave to the hard disk)
HL-DT-ST GCE-8400 CD-R/RW (as SCSI, the usual thing with CD-R)
Logitech USB wheelmouse
PS-2 keyboard
Sound card: Choose from SB live 4.1, SB live 5.1, SB live Audigy2, Via8235 AC97 onboard chip.
Serial external 56kbps modem

My trouble is that

a. Using the SB live (any of the two), the sound output keeps repeating itself (except for xmms) unless I move the mouse. At first I thought it's an irq conflict, so I tried connecting the mouse in another usb port. No luck. I ran a cat /proc/interrupts and here's the output
0: 907872 XT-PIC timer
1: 15853 XT-PIC keyboard
2: 0 XT-PIC cascade
4: 224227 XT-PIC serial
5: 0 XT-PIC usb-uhci
8: 2 XT-PIC rtc
9: 0 XT-PIC acpi
10: 83356 XT-PIC usb-uhci, EMU10K1
11: 0 XT-PIC usb-uhci, radeon@PCI:1:0:0
12: 0 XT-PIC ehci-hcd
14: 29705 XT-PIC ide0
15: 108 XT-PIC ide1
NMI: 0
LOC: 0
ERR: 0
MIS: 0

You'd think there's an irq conflict. Well, I can assure you that there isn't. I disabled usb support from bios (I had the option so I tried it). No electric current going to usb AT ALL (I checked it with the mouse) The usb-uhci entries disappeared, the problem remained. The trouble isn't so much the mp3's (xmms plays fine). The thing is that I'm trying to set up my comp so that I can watch movies (DVD or AVI's shot with my digital camera). Xine is just hopeless, as the sound keeps repeating (I use the term "sticks". It's like what happens with old vilyl records, where the needle keeps jumping back in an endless loop) and eventually it crashes.

I'm not even mentioning the other two sound devices. Audigy is a disaster (no sound at all, and a lot of complaints) and the sound chip, well... no complaints, but no sound either. Xmms seems to visualise sound, but nothing is coming out. It's not a mixer problem, as the SB live test has proven (I get sound in xmms with the SB live cards).

b. My DVD-ROM doesnt mount AT ALL!!! Here's the fstab:
dev/hda2 / ext3 defaults 1 1
/dev/hda1 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbdevfs /proc/bus/usb usbdevfs noauto 0 0
/dev/cdrecorder /media/cdrecorder auto ro,noauto,user,exec 0 0
/dev/dvd /media/dvd auto ro,noauto,user,exec 0 0
/dev/fd0 /media/floppy auto noauto,user,sync 0 0
/dev/dvd /media/cdrom auto ro,noauto,user,exec 0 0

The last line was added by me manually. Any help with this would be greatly appreciated, as I currently have to mount my CD's on my CD-R, and I'd like to see the DVD/CD-ROM work for a change!!! (mind you, there is power going to it, and the cable is correctly connected).

I can post the output of any command (lspci, lsusb, etc) on demand.

Thanks in advance

try mounting /dev/hdd (or /dev/hdc) to /media/dvd ... try it with a standard CD ... i haven't delved into dvd mounting really.
If that works, your symlink to /dev/dvd is broken.
