changing RDL of a snapshot?

As I understand it, once you snapshot a report, any changes to the RDL of the
report will not affect the snapshot. Let's say (using a purely hypothetical
situation ;-) that I misspelled the text of a column header. Has anyone
looked into messing with the stuff in the ChunkData table to go change a
piece of text in the RDL of the snapshotted report? Obviously this would be a
completely unsupported action as far as Microsoft is concerned... and I would
obviously proceed at my own risk.
Can anyone give me any hints about what format the ChunkData.Content column
is in so that I could read and modify a few bytes?You are right - this is an unsupported action.
BTW: you won't find *any* RDL XML in snapshots. Snapshots are output-format
independent, already processed reports. The risk is extremely high to get it
wrong when messing with them (in particular for compressed snapshots on
SP1). If you get it wrong, the snapshot is no longer usable and will result
in a fatal error "unexpected error during processing".
Keep in mind that you are on your own once you modify anything directly in
the report server databases.
