To see whether the file on the DVD might be corrupt, I copied it from the DVD and also downloaded the same file from one of the YDL mirrors. MD5 checksums of both files are identical, so it has not become corrupt during my download and burning process.
I believe the issue you are encountering are with burning specifications. When burning the disc, ensure you are using the joliet specification to burn so you are able to have file names up to 64 characters. You may have to use something like Nero(Windows) or maybe Toast(Mac) to burn the ISO image. Just look for something that says joliet and check/enable it.

1. The master copy of the file is corrupt and has been distributed with that corruption.
2. There's something particular about my machine (the model, the configuration or perhaps a hardware fault) which is causing install to fail.
In order to rule out the first (less likely) option, I have asked whether anybody else has successfully installed YDL 6.1 on an aluminium PowerBook G4. I'd also be interested in alternative methods of installation, if any exist. Otherwise I'll probably just give up on my little experiment.
The master copy is not corrupt that much I can say. I've extracted the exact ISO image using winimage and the file name is complete. I don't have an aluminum PB G4 but I can suggest the net installation method as an alternative. Having just completed installing YDL 6.1 on my Xserve G4(CD-Rom drive only), I'm pretty happy with how it went. It was my first time using the net install method for any linux distro and I have to say it was daunting at first, but in hindsight it wasn't so bad. Here's a quick step by step:
(Requirements: local web server, YDL DVD ISO)
1. Extract the contents of the ISO to a folder that sits at the root of your webserver.
2. Burn the boot.iso file from the <ydl iso folder>/images/boot.iso
3. Boot your computer from the disc made in step 2.
4. Hit enter when you see the prompt "Boot: "
5. After configuring your network, you will be asked where the YDL files are located, use HTTP and specify the address of your webserver and the folder name set in step 1.
That's it and the installation continues as normal from there. Hope this helps!
