Hi there: After searching the forum, I couldn't find anything that exactly duplicated my issue, so I thought I'd post here. I have been using IFOEdit for quite some time now an an old Duron 900 machine with WinXP Pro with no problems whatsoever. I just upgraded to a XP2200, with WinXP Pro SP1, and I'm having some issues. Here's my setup: ASUS7V333 512Mb PC2700 Athlon XP2200 WinXP Pro SP1 I know that Derrow has admitted that there are issues with XP, but I find it odd that it's only in some places. Like I said, I had it working before. Anyway, I seem to be able to edit ifos with no problem, changing first-plays, getting VTS Sectors, etc ... However, when I try to strip streams, or create ifos, it opens the two dialogs (open, and save) and then just sits there. It doesn't do anything. Here's what I've tried: - Changed from NTFS to FAT 32 (no luck) - Running in all the different compatibility modes (no luck) - using previous releases of IFOEdit (also nada) Has anyone seen/fixed this? Or am I going to have to wait for the XP Certified release? Anyone know when this is expected? Is this the 10/14 one? Derrow, thanks for all your hard work. You really don't appreciate what you have until it's gone. I'll be sending in my donation to speed along the XP release.
