_Streams is not a real table. The documentation states "This is a temporary
table, created only when referenced by a SQL statement." The CABs are
actually stored as separate streams in the OLE Structured Storage file. You
can see them with the DocFile Viewer (dfview.exe) from Visual Studio 6.0 (it
may be included in later versions but I can't see it) but that's not really
very helpful as the names of the streams are mangled.
If you want to change the compression level, change the CompressionLevel
attribute. However, here, I think that you've misunderstood DiskId. Only the
files marked with the same DiskId are included in the specified CAB file.
I'm not sure if there's any point making multiple embedded CABs, although it
is possible to request light.exe to reuse existing CAB files.

But there is no _Streams table and the file size is only 70K which is
essentially the same size as without compression.
Does WIX2.0 not support this, or am I missing something?
Thanks,
