O.K. I'm Old/no Techie....how do I

you'll need to get over your hard drive phobia first. then grab a PS Audio PWD and Bridge. Buy a large high speed hard drive for your existing computer (pc or laptop). load your music onto the new drive and you're there!. the bridge will do hi-res and internet radio. forget the wires and go wifi from your computer to the PWD/Bridge. the sound quality is incredible imho. there are still a few bugs some folks are experiencing but in general, the set-up is phenomenal.

I tried to load flac on a DVD and play it on my Oppo BPD83 SE but with no success.

If you want the very best result, then get a Mac Mini, even a used on on ebay. Put Pure Music on it and play back through a USB DAC. Like all DAC's USB DACs vary a lot in sound quality. The important thing with digital is to put your money where the clock is, that is the Master Clock. For CD's, this is in the Transport. In the case of the USB DAC, it's in the USB interface.

I heartily agree with the Mac Mini. Notebooks have LOTS of noise (primarily from the monitor) which screw up the sound. No depth, air...all confused...true of all notebooks.

Some DACs or players like the Oppo 95 allow you to play high rez FLAC from a USB thumb drive. This seems like a good solution for those of us who don't want to hook up a laptop to our stereos.
Also you can burn DVD-As from high rez files, although my old player has a hard time reading these. Also I think there's a 24/96 limit to DVD-A, so you might not be able to copy 24/192 files to a disc.
