I'm having the same issue. I recently did some system upgrades but had tried 7.x out on my old system sometime after it was first released. At the time I wasn't finding all the hits that are on Google/Yahoo now. I ended up just downgrading to whatever the latest 6.x version was at the time and it worked fine again.
The old system was an MSI Neo2 Platinum nforce3 board with an ATI x800 Pro and an Audigy 2 Platinum card in it. The rest of my system is the same and here's current specs: Mobo:
Asus A8R32-MVP (ATI Chipset) Proc:
AMD 64 3500 Video:
Sapphire x1900xtx Monitors:
Dell 2005FPW & 2001FP RAM:
2 GB Crucial HDs:
160GBx2 SATA NCQ Seagate Barracuda RAID:
ULI Chipset (RAID 0) Audio:
X-Fi Platinum Burner:
Plextor PX-712A DVDR
Not sure if anyone else is using the ATI or ULI chipset. I have not tried replacing the MP3Pro.dll as of yet but I can say if I revert to the latest Nero 6.x it works fine, even tho I've seen something about going back to 2.4.8 and it still being an issue (maybe just on the file, as it works fine in 6.x for me). OS:
I ran XP Pro SP1 on the old system and ended giving in to SP2 on the new one. Software (What I can tell runs memory resident items or media related):
- MusicMatch 8.x (hate the new ones)
- WinAMP 5.2
- iTunes (latest)
- SystemWorks 2006 (2004 on old)
- Latest Video, Audio & Mobo
- iPod Service (had issues without iPod or iTunes tho)
- zBoard keyboard
- Logitech G15 keyboard
- Daemon Tools.
Also, I have an older Asus nforce2 board with an AMD 2500 as my second system (that I do most of my burning from) and it had the same issue with 7.x so I went back to 6.x.
Not sure of anything specific but I know there are a lot of free "task tools" out there that that will identify what you have running in memory. Something perhaps on SysInternals
As for it not being a Nero issue, it has to be something with drivers or other apps that are installed causing the issue. Had a similar problem with xFire last year and in-game messaging not working and no workaround so I played around until I found an issue with newer ATI drivers...I replaced files from a working system to the non-working system one by one and found what files caused it to basically crash the in-game chat support (it was different if you built a new system and installed vs. if you updated drivers)... Got it submitted, worked with a developer for a week or so until he zeroed in further (on the code side) and they released an update. Basically something changed in drivers that they utilized and while xFires didn't create the issue, they still needed to get it fixed for their software to work properly.
Mp3Mogul, anything there that you've not tested with or other people see any common apps? Could be a lot of things but I thought I'd register and add my system specs to the list. :)
