Some Backup Issues With No-Solder R-Mod

[trilidar]

Me again. I've kinda noticed something odd with my R-Mod that I'm hoping somebody can help with.

I have a few DVD backups that just refuse to work. They either boot and then crash or just hang upon bootup. What's odd is that some are EA titles (SSX Tricky, 007), however I can backup and play EA CD titles (Madden, FIFA) with no patches or problems.

What I'm wondering is: is this a known issue or do I have to do some 'super secret' boot method for these? I've been using NightStalkers excellent boot method with a GS2.x, so if you happen to know I'd greatly appreciate.

Thanks much in advance
