Thanks again for this. I think some of my reciprocal glumness stems from an ill-worded thread title. I have a plan now, so for the record here it is:
I aint no recording engineer, but manage to successfully record LPs (for my purposes) using my turntable, amplifier, suitable cable, bog-standard-came-with-the-PC sound card (probably crap), Adobe Audition and MC for archiving. The problem was advising someone else how to do this.
1. We've established that an appliance DVD recorder is a non starter. This was the area where I was totally clueless. It was supposedly an 'expert' in the friend of a friend sense who recommended this BTW. Engaging a professional I suspect will cost more than its worth even given any sentimental value - my Dad was a goatee-stroking poloneck-wearing jazz buff in the late 50s and 60s who recorded a lot of music which he has kept. They have effectively been unlistenable for years due to the tape format.
2. My fathers clueless zone on the other hand extends around his PC. I suspect downloading and installing software might be difficult to supervise remotely. They play CDs using Windows media player - not ripped, just the CDs. Audio compression and ripping etc are a mystery to them so far. Im sure their sound card isnt up to much either.
3. My recommendation to him: forget the DVD thing, concentrate on connecting the tape deck to the PC.
4. Next, we test that we can record a signal on the PC. We use the built in Windows recording facilities. All we need is to be able to record a minute or so as a proof of concept. Even at low quality, hopefully it'll be enough to demonstrate it works. If we get silence I suspect even an install of MC wont work (although not so sure of this).
5. If 4 is successful we are at the point where we need to learn about installing proper software and sorting out levels plus, further down the line, explaining audio compression formats etc.
Actually, I have realised that in addition to the media editor, MC11 has a record sound facility in a single dialog (albeit you might need to tweak some recording options first). Not tried this, but what could be simpler? Maybe Ive answered my own question.
So to close this magum opus, thats where I am and thanks again jgreen, really grateful for the help.
