PDITool vs. pdi2iso - ISO File size

[homey]

I just used the above two tools to convert an Instant Copy rip to .ISO. The file sizes are not the same.

PDITool = 4,516,657,152
PDI2ISO = 4,516,724,736

The contents are the same. Both have video_ts and audio_ts directories. Both mount and play just fine using Daemon tools. As you can see, there's a difference of almost 70k.

Is this anything to be concerned about?

Did you compare the files to see where the difference is? Or are all the files different sizes?

If I open the .ISOs and compare individual files, all files are the same size. The sum of all the files contained in both the ISOs are the same. It's the size of the ISOs themselves that are not equal.

Strangest thing.

The difference is explained very easy:

pdi2iso just strips the header from the .pdi-files and pads the resulting file to be a multiple of 2048. It does not look into the structures and therefor copies some padding as well.

pdixtract (the engine of pditool) analyses the directory structure of the pinnacle generated iso inside the .pdi file set and copies everything up to the end of the last file.

Short version: the difference is just padding, nothing assigned to a file.
