90min CDRs do not hold 870MBs.
Here are the specs for a 90min CD.
CD-R Type / Overburn Capacity / Capacity in MB
CD-R 90 / 92:30 Minutes / 800 MB
Some 90min CDRs will hold 820MBs. 99min CDRs are required for holding 880MBs. You will never be able to squeeze out the whole 820MB since a few megs are used for CD file system overhead.
90min and 99min CDRs are not recognized as such on most burning software. You will need to 'overburn' to achieve the media's full capacity. However, you might try running your media through CloneCD to see if you get any better results in detecting its true capacity.
