Error when copying information from DVD-R

I'm running freeaxp on windows vista, I have a .sav file I am attempting to copy over. Every time I try, I get the following error:
Error opening dka100:[000000]backup.sav;1
-RMS-F-ALQ, invalid allocation quantity (negative, or 0 on $extend)

I apologize for asking so many questions.

It looks like a file or file header corruption problem. Try an ANALYZE/RMS on the file.

Well I ran the command, only to find out that the .sav file is compressed. Could it be an issue between it being compressed and then transferred to a windows machine? I tried to use the .sav uncompressed and come to find out it was too big for the iso file format. I was thinking I could inject the file into one of the virtual disks I have, but I haven't been able to find a way to do this.

Can you provide details on where and how the .sav file was created? Is it a VMS backup save set or something else?

I backed it up from my VMS Machine using VMS. It created a compressed save set, then I FTP'd it to a windows machine using binary. Then I burned it to a disc using cdxp . This is the second time I've done it and I'm still having issues.

What command did you use to create the save set?
