You will always get people who have had bad experiences with factory cassettes onto which they have taped fresh film but my experience has been like railwayman3. It has always worked OK. If the factory cassette has only been used once and the film from that was OK i.e. no scratches, then why should the felt suddenly give problems?

I wouldn't use the factory cassettes more than say 3-4 times before dumping but if you live near a mini-lab then at least you are making use of cassettes that otherwise end up in landfill sites after single use.
