Sounds like powerpoint might strip off some of the OLE stuff when it embeds it, or possibly have had some more stuff wrapped around it

Once you've decomressed it, try comparing it to the thing you originally embeded. You might find that the decompressed stream starts part way into the original (and hence stuff was stripped off when embeding), or that the original starts part way into the decomressed stream (and hence extra stuff was added)

Do let us know what you find, so we can include it in a future HSLF version
