Viewing every single TFS changeset?

I am trying to view every single changeset in my project's history... at least the last 1000, say. So I ran the command:

tf history $/MyProject /recursive /format:brief

... at the VS command line. This popped up a history window with most of the changesets in the MyProject project, but even here there si the odd changeset missing. For example, the list of changeset IDs goes: 3956 3955 3954 3953 3952 3949 3948 3947 [...]

Changesets 3950-3951 are not shown; why? And how can I force them to开发者_如何学JAVA be shown?

Change set numbers are shared on the server level. Maybe those change sets are part of another project?

EDIT: shared on the collection level since TFS 2010
