I recently upgraded my HDD to a bigger one and backed up my DVDs with DVDShrink for more convenient viewing. I connect through XBMSP, which has been working well so far with all my media.

I only now discovered that some of the ISO files don't mount in XBMC when I click on them. My first thought was that some of them are too big for XBMC to handle, but this doesn't seem to be the case since many big ISO files mount without problems. All of smaller ISO files mount, but some of the bigger ones don't.

There isn't anything wrong with the ISO files either, I can easily list, mount and extract them on my PC. At the moment I have to extract the non-working ISO's to directories and play the ifo file, but this really isn't the ideal way.

So, any help would be appreciated.

try one of the "not working" ISOs while in debug mode, then post your log like it says...
