Boot disc not progressing

[PSXissues]

Stuck on the screen that appears after trying to boot the disc. Unirom is booting fine, but it cannot get past the boot disc screen and simply says "Seeking 2". Occurs with multiple types of CD R disc, written at different write speeds. Is not completely frozen either as unclosing the disc drive reverts it back to the initial stage in the booting process where it asks for the disc drive to be closed.
SCHP 1002 2.2 bios PAL 2nd slot.
Installed to Mcard via Mcardannihiliator on PS2.

I recently had a Seeking 2 error, but it was due to using CD-RW discs, CD-Rs seem to work just fine at 4x burn speed for me.
But this was on NTSC consoles, not PAL. There is, sometimes, strange behavior when a memory card with corrupted data is in slot 1. I tried taking out my Memory Card from slot 1 and then I removed my Memory Card in slot 2 when the reminder text came up before booting the game and that seemed to help me progress. Not sure if this will help you, but I thought I would chime in, regardless.
