You might want to take a look at the atomic refresh option. If I remember correctly, the default value change in 10g.
Also, take a look at Doc 365157.1
We had to specify atomic_refresh=>FALSE in the refresh.
Let me know if you have questions.

Subject: Materialized Views 9i vs 10g
I am taking Materialized Views that were initially built on a 9i database and rebuilding them on a 10g database - verbatim. I am noticing that the performance is noticeably degraded. Checked out the Explain Plan on 9i vs 10g for some the materialized views, and they would indicate that on 10g, the materialized views should at least perform the same OR performance should be approved. Any ideas would be appreciated.
