cdrecord multisession not working 4320

When you use both the -M and -C options to mkisofs, an ISO image that isn't a "full" ISO image is created. This image starts at the sector marked with -C , and is -Merged with the existing ISO on the device you specified to -M. Take a look at the output of mkisofs when you've used -M and -C; it'll consist of 0x00 up to the point where -C starts.

Nope. See first paragraph for why. You may be able to feed mount the session= and-or sbsector= options to get it working if you think you need to do that. The sbsector= parameter should be available from the -msinfo command you executed with cdrecord.

You shouldn't really need to mount the image with loopback. The whole multisession thing has been well-understood for a while, so the mkisofs output should be fine no matter what.

Also, remember that multisession ISO9660 has overhead. You can burn at most about 40 sessions to a CD, so burning small chunks of data is not really optimal.
