Crazy PS2?

[SleeplessHunter]

hey guys! new member here, so trying to start off w/ a bang :P

First of, I got a new (?) V4 PS2 which was like 2 months ago.
I bought GT3 and it runs perfectly.

Now, comes the fun stuff.
I bought a flip-top cover, installed it, and it was too noisy. So, I took it off, fixed it properly, and now its quiet like it should be.

I just bought an LG 4082B DVD-writer, and Verbatim Data Life (not plus) DVD-R's.

So, I go to copy my first game, Spiderman 2, I have the image file o-sm2.iso, and I use DVD Decrypter (at 1x of course).

I use swap magic 3.0/2.0(dvds) and put in the spiderman backup, and it takes like 3minutes for it to just get to the memory card check screen! What I hear, is the disc spinning, laser reading, then stopping. Spin, read, stop. Over and over.

So, then I decide to try to burn Psi-Ops. So I burn it using Nero this time, and it burns perfectly and works perfectly!
So im happy thinking it was just a bad burn, so I retry spiderman2 w/ nero, again at 1x, and this time it loads faster, but still skips...
I can hear the spin/read/stop process happening again for the re-burn of spiderman2, and while I CAN get ingame, the ingame help voice, stutters like crazyy, and all the intro movies jump and skip incredibly and I dunno why.

So I re-try psi-ops to make sure nothing happened, and then IT starts jumping and freezing! (which was working perfectly just before)
Then I burn Jak 2 and it works perfectly, loaded fine, no jumps.
And so I try Psi-Ops again and it was working ok, just taking some time.

So I have to ask... IS my PS2 possessed?

Whats the problem here?

Im very confused and need help...

Thanks in advance!
