I tried to record all of Avatar (Only recorded Front Channels with +3dB on all channels, no LFE configured, all set large from G68 out). My laptop went to sleep about 1.75 hrs in.

It looked pretty darn good. It did clip mildly about 1/2 a dozen times in the low frequencies. Maybe 100 samples out of ~300,000,000 samples. A little clipping is fine (you might even say it's a good sign to clip a little because if it doesn't clip just a little it means your not pushing it to the max dynamic range).

I did record the THX logo. It clipped more significantly. Then I turned LFE on and looked at the data "unclipped" and the orginal audio has modest clipping built in (lots of flat top peaks below full scale). It is not nearly as tidy as the movie itself. Basically it has a lot of flat top peaks that are not at full scale (it was clipped in prior mixing). That logo has probably been transferred a few times. It sounds fine with or without LFE configured though.

I mentioned I could not record from HD621. I can. It was the EMU refusing to record at 48Khz. The TASCAM records anything with encryption off. All I do is set non 24/96 speakers and plug TASCAM into the output of the DSP speaker and I'm ready to record.

If you think listening to music is fun, try learning an instrument.
