As a general principle I know you should not encode a signal twice, so I always copy to the HDD in the compression mode I'm going to use when writing to DVD.
However I read on another thread that the Sony HQ+ mode is designed in a way that if you record to the HDD using this then re-sample down to the bitrate that fits the DVD, you get a better encoding than going straight from the broadcast to final mpeg. I can't see this in the manual or elsewhere and can only quess that this is like doing a two-pass encoding somehow.
Does anyone know if this is true and why it would be so? Has anyone had the time to do some tests to see if it is better this way? If not I will try to find the time to do experiments myself, but that could take a while and I would really like a technical explaination.
Thanks
