I wonder if the limit on lines was due to 20 kHz filters on the audio output. When the 24/96 audio sampling & perception discussion went by a few weeks ago I seem to recall some testing showing that even high sample rate sound hardware had low pass filters just above 20 kHz. This kind of issue should have been easy to spot in development and testing, though, so maybe just a limitation of the medium. I've got an old hobbyist oscilloscope, it was my former boss and mentor's first scope. I really should hack up something with it along with some of these low cost cpu boards.
