I'll try out the beta (Thanks again for the link).
I'm probably going to stay with iTunes 9 just for the fact it's a whole lot faster than the old one.
If nothing works, then perhaps with a patch or something later down along the line I'll be able to use my LimeWire Tunes playlist.

If the Beta doesn't work then you could also try a LW 4 version, as long as you're happy to use LW 4. Who knows where the incompatibility is - just maybe LW 4 won't have the same issue.

If you want to try LW 4 then check out this thread for links: Downgrading to LimeWire 4 from 5 & resuming incomplete downloads

If it's an issue with iTunes 9 then the LW developers will be notified & they can look into it.

Edit: Please let us know whether changing LW versions fixes the problem. Thanks.

I'm using Win XP, updated iTunes & QuickTime to most recent & using LW 5.2.13 & no problems with the user playlist showing in iTunes including music & video. Unlike LW 4, you do not see Library & user lists, instead you simply see the user shared playlist with drop down arrow.

* For the songs to appear in the shared user list in iTunes, it appears they need to be shared in LW. I think that means it operates differently to previous versions of LW which from memory showed all recently downloaded music. Under LW's Tools -> Options menu scroll down to iTunes options button & ensure share with iTunes is enabled.

Using another Win XP with updated iTunes & QuickTime & LW 5.3.4 Beta, the other account's LW playlist (one mentioned at of post) shows up fine as does the LW 5.3.4 playlist, and another from a mac computer.

Generally after installing/updating QuickTime you should reboot your computer.

Ok, after downgrading to LW 4, I got a message saying that "Matt's LimeWire Tunes are not compatable with this version of iTunes." So it's a no go with the downgrade.

I'll upgrade to the beta version again, and I'll ensure that all of my library is shared.

Both LW 5 versions should work fine. LW 4 does have that issue with the later iTunes versions.

After upgrading to LimeWire 5 and ensuring that all my LimeWire files are shared, I can now access all of my LimeWire though the "Matt's LimeWire Tunes" playlist!

Thank you SO much birdy and Lord Of The Rings, you guys were amazing.
EXCELLENT support on this place, and if I've got any more troubles, I won't hesitate to ask!

I told him to do that earlier - sharing was enabled

I just updated to iTunes 9 as a test. My options are ticked to allow sharing with iTunes. My 'LimeWire Tunes' shows as per usual.

But - if I don't have files showing in Public Shared in My Library (ie being shared with the world), they don't show in my LimeWire Tunes in iTunes.
Add everything to Public Shared & it shows up in the LW playlist in iTunes. So looks like it's not just iTunes sharing within Options but adding to Public Shared as well.

Yeah, seems that way.

Everything is working perfectly now. Just gotta remember in the future that everything needs to actually be set to shared in my library. Thanks again, guys.
Hope this helps other people, too. :P
