Blocking issue in DTS package running on 2005

I'm testing an existing 2000 DTS package in 2005. A Data Transformation Task selects from a view and loads a table that was just truncated. The view definition contains a subselect selecting data off the table,

View: select ... from a, (select ... from b) b2 ON ...

Table to insert into: b

There is blocking going on during the execution of the package. The select * from view (Source) and the insert bulk into the table (Destination) are blocking each other. This does not happen in 2000.

Is there a command that I can put in the view definition subselect that will allow me to just grab the data that it can without worrying about blocking? Would READCOMMITTED or READUNCOMMITED work without impact on the view? Other recommendations?

Has anyone ever run into this?

I found that when you uncheck the Table Lock box of the Data Transformation Task, that this blocking does not occur. Does anyone know why this is required in 2005 but works fine in 2000 with the box checked?
