What EddyCurrent said but also...

But that's not the answer to your question - he may *say* it BUFFERS but that's exactly what it isn't doing. Buffering means that rather than loading ALL the data from the stick to internal memory and then running it (what they call "internal"), BUFFERING (in this context) means it should load "some amount" from the stick to internal memory and then as it works through it it loads more as needed until the job is done (what they call "external").

You're being fobbed off by someone who either doesn't know or DOES know and is not prepared to admit that it doesn't do what the manual says it should.
