OK.For starters, while alcohol 120% is ok.... it ain't perfect. Used to trust it 100% (get the irony!!) until i found a bug in it...It doesn't burn .cue and .bin files correctly.
U must use Record Now Max or DX to ensure a 100% correct burn for DVD's every time.
Ritek G04 are the best so u have correct media.
How old is your version 9?
Mine lasted 6 months of playing DVD backups ( about 1 hour a day) before the laser started to not read dvd-r's (ritek g04).
If u in the same position then a "Minor adjustment" is needed.
I'm Not touching the laser pot!!! I hear u scream. No need to....Heres what to do...
Firstly unscrew the 8 screws on the underside of the ps2. Tkae the top ps2 cover off.
Next undo the 2 screws on the dvd drive lid. use a knife to lever out the two catches on the back of the dvd drive lid and remove lid.
At the back of the drive u will see two whit cogs that adjust the height of the rails that the laser head sits on. look in siodeways and try to understand how they work. By adjusting the gogs, u adjust the height of the rails and therefore adjust the height/closeness to cd/dvd of the laser.
Adjust it to the lowest position, put in an original dvd and boot.
Adjust both sides one click up and boot again.
Repeat until game starts to boot.
Keep going up until game won't boot again.
Count the clicks from lowest measurement until highest measurement that dvd will boot (should be about a bracket of 13-15 clicks).
Adjust to the middle cog click of the booting bracket, check that original cd will boot. If not adjust a few clicks above or below the middle bracket until cd does boot.
When u in a position where original cd and dvd will boot perfectly try backup cd and dvd.
If they don't boot adjust one click towards the disc at a time (within the working bracket) until they do boot.
If u go through the working bracket and u still get no boot then Its time to pot adjust.

Measure the resistance of the dvd pot and adjust it by 50 ohms down.
After doing this go back to the beginning of adjusting the height and start again.
U can do several adjustments to the pot but don't lower the resistance by more than 10% of the original value.
This is a time consuming exercise but do not rush it and do not stab in the dark on yr adjustments.
I would also recommend that the romeo mod be carried out on all v9/v10 ps2's b4 any laser adjustment takes place.
This advice is given as purely advice. Any adjustment that u make to ur own PS2 is yr decision and yr responsibility and i accept no blame for anyone who rushes it and messes it up.
Regards
