Subject: splitting tar.gz files

Hello all,
I need to split up large tar.gz files into CD-sized volumes for burning to CDs. The data is about 12 GB uncompressed, and about 6 GB compressed. In the past, I have used WinRAR to do this on Windows (with .rar files, not .tar.gz), but now I need to figure out how to do it with Linux (command-line only). tar.gz is preferred, although I can use some other format if it provides a better solution.
So far I have came up with several solutions, but none are really ideal.
1) tar and gzip normally, then use 'split' - this is okay, but to extract files, I would have to cat them back together into one big file again. A lot of work if I only need one or two files.
2) tar using -M and then gzip the separate files - if I split into CD-sized files, then gzip, there is lots of CD space wasted. Or if I try to guess the compression amount, there's a good chance I will end up with several volumes that won't fit onto a CD and will have to redo the operation several times.
3) gzip all the files first, then tar them using -M - this works okay, but each and every file then needs to be ungzipped after extracting the tar file - not practical for a large # of files (unless I can come up with a script that can do this automagically)
4) tar and gzip normally, and then tar again using -M - this would work like I want it, but it's kind of convoluted having to tar twice
Any better ideas, or suggestions?
Thanks,
Justin
