I/O Error Toast Result Code = -36

[pastark]

I have several video files from a school play. I converted them to mpeg2 files which play perfectly in QuickTime, no synch problems, everything seems fine.

When I try to burn them to DVD-R using Toast, it runs through the "preparing" sequence, but then when it begins to encode, at some point I get "Unable to complete the last command due to an i/o error. Result code = -36."

As far as I can tell by testing using standard tools, the hard drive(s) and the files are not corrupt.

I have never gotten this error code before.

Can anyone elucidate or suggest a solution?

Thanks!

demux them into streams, use sizzle to compile a DVD image, burn the image with toast.

Thanks.

I'm trying the mpeg2 files because the elementary streams didn't work, same error code.

On Roxio's website, someone asks about this error in the forums, and their guy says, "It's having difficulty reading the file from your hard drive."

The -36 error is an OS file system error, not a Toast error. Toast is having trouble reading the file. Do you have it on the internal or an external drive? Does its permissions allow it to be copied?

Frobozz,

Thanks. I tried saving a disk image from the files in a folder on the same drive as the system and also from a folder on an external drive, same result.

Then I tried saving a new disk image of a movie I've already burned successfully. Same result.

I tested the drives using TechTool and several other utilities packages, and nowhere do I get a hint of any errors communicating with the drives.

The movies play in Quicktime flawlessly, without any hesitations or glitches.

It occurs to me that this is the first disk I've tried to burn since upgrading to 10.3.3.

Thanks again.

Try repairing your permissions using Disk Utility. You launch Disk Utility, select the drive in question, and hit the 'repair permissions' button, and away it goes. See if that makes a difference.

WiseWeasel:

Your suggestion worked. When I repaired permissions, a few things were altered, and two restarts later, the problem vanished.

Another contributing factor seems to be non-compliant .mp2 stream files. I've converted sound from .mp3 or other formats to .mp2 using SoundConverter or ffmpegx (where I'm adding music, for instance). I find that if I convert to .mpeg sound files instead, compliance issues vanish. I don't hear any difference in quality, but I'm not using a high quality TV to check these out.

SoundConverter is amazingly fast and convenient, but its output is sometimes strange... if I try to boost volume, the result is a file that sounds louder but that also has electronic squeaks, bangs, booms, screeches, and other extraneous noises along the way.

But all in all, your suggestion worked. Thanks!
