Trouble with Region-x disk

[wildthing]

Hi there, had my chipped PS2(NEO 2.2) & Region-X disk for 3 weeks now, & everything was OK until last night.Before when I inserted RegionX disk & pressed reset the disk booted straight up without going to the PS2 browser/configuration screen.Now whenever I boot any disk (PS2 original/PS1 original/PS1 backup/DVD video) my console boots to the browser screen,pauses for about 20 seconds & then boots the disk. The RegionX disk won't boot at all & so I can't play any PS2 backups.I've been told that the PS2 doesn't recognise the RegionX disk from the browser screen & it has to be booted straight from standby but like I said no disks will boot up straight from standby without going to the PS2 browser screen. Just wondering if anybodys had anything similar happen. The PS2 & chip are under guarantee but I don't know if the problems with the hardware or the RegionX disk. Any helpful replies would be appreciated.
