But there is a re-occuring question about this area. It appear that the software in the TV does a speed check and if the USB thing is not fast enough, it does not work. Furthermore I've heard it does not pop up and tell the person it's too slow.
I can see why this would result in your question.
there is a record button on the remote control and loads od reviews say this can be done but the Samsung manuals don't explain how to do this. Please help. Thanks Andy
