AAC 128 Conversion Error -50

I am attempting to sync my iTunes library to my iPhone and iPad using the 128 kbs ACC conversion option. Most content seems to sync fine, but there is a specific song that the AAC converter seems to get stuck on with an "unknown error -50", and causes the sync to fail. I am sure I can "manually manage music and videos" to get around syncing this specific song, but that isn't a decent solution for me.

What I have tried:

Manually converting the offending song to 128 AAC using the Acvanced - Convert to AAC option, and the manual conversion outside of the sync process fails.

Rename the song, because the song and the album share the same name.

Neither option have helped.

Mac Mini / iMac 21.5 3.06, Mac OS X (10.6.2)

Does your iPhone wipe out all of your song and resync / convert them all each time you sync your phone? I am having this problem, as well as some others (in another thread).

No. It only tries to convert songs that are already not present on the device.

Do you have LYRICS embeeded in your songs? I'm trying to figure out why some people are having this problem and others are not. It appears that lyrics may have something to do with this.

And thus we have found the source of the issue!

Let's hope 9.1.2 comes out soon and fixes 128 kbps conversion with lyrics YET AGAIN. 😟

Maybe I'm confused, but I do not have lyrics embedded in any of my songs, including this one.

There are TWO issues - the issue you are having in your first post, and the issue of songs with lyrics being reconverted everytime the device is synced if 128 kbps is checked. I'm talking about the latter issue.

I started by getting this error...

"iTunes could not copy "xxx" to the iPhone "my iphone name" because an unknown error occurred (-50)."

Happens on a few songs (and halts the sync operation). The songs play fine on the Mac and I can find no issue with the actual file itself on the disk - it just won't transfer to the iPhone.

So after searching, I linked this error to the conversion to 128 kbps AAC. I tried converting one of the offending songs, and get a similar error.

Songs have no embedded lyrics (but do have artwork).

Out of > 4,500 songs (~23 Gb) it seems there's less than a dozen that cause this issue.

Same issue for me. I can live without those songs being on my iPod but the fact that it keeps stopping the sync is really annoying. Anyone got a solution?

I have this same error. iPod Classic 160gb(can we get a bigger model please apple?)using iTunes 10 with the same issue. Are they even working on a fix for this? I'd love to be able to free up some space since I don't think I'll see a bigger model any time soon.

Same thing for me ! With new iPod Nano, iTunes 10. No lyrics. The problem seems to be with .mp3 files.
