I've never seen the ADSTech device in the flesh, but looking at their
website, it appears to simply be a USB soundcard, and a fairly cheap
one at that. There are literally dozens of similar devices available
from a host of manufacturers. Creative make them, as do M-Audio,
Terratec, the list goes on. The ADSTech device might be great - I have
no idea. But it could also be garbage (as maggior has suggested). If
you want a USB soundcard, then it is probably safer to buy a reputable
brand. The M-Audio Transit is well-regarded and not too expensive. If
you definitely want a cheap one, then I'd think something like the
Creative Soundblaster Connect or Soundblaster Surround 5.1 would be a
safer buy. (Not that I'd personally buy a Creative soundcard, but they
are widely available and are known to work OK).

Regardless of which soundcard you buy, you're not limited to using the
bundled software. Pretty much any recording program will be able to
make use of pretty much any soundcard.

Regarding the process of recording first to your DVD and then
transferring from there. Firstly, I strongly suspect that the audio
that gets recorded by the DVD player is the standard AC3 codec used on
video DVDs, which is a lossy compressed format. It's normally sampled
at 48kHz, and that is no problem encoding to FLAC. (Only if you wanted
to burn it to an audio format CDR would you need to convert to
44.1kHz). Incidentally, how are you extracting the audio from the DVD,
and then how do you convert the AC3 to FLAC?

Recording directly to a PC without going via this intermediate step
means you can record straight to uncompressed WAV format, retaining the
maximum possible sound quality.

The inside of a PC is a very noisy environment, but contrary to
intuition, modern internal (PCI bus) soundcards are amazingly
invulnerable to it. For example, the M-Audio AP2496 has a noise floor
of about -93dB. Cards like the Lynx2 and DAL Card Deluxe manage well
below -110dB. Even the humble Creative Audigy can get down to below
-80dB. These sort of noise floor figures are more than enough to cope
with the signal from vinyl (which has a typical noise floor around
-60dB, if you're lucky).

So if you have a desktop PC, a decent PCI bus soundcard will give you
the best sound quality at a given price point. (But avoid using
on-board sound - that is usually a bit dodgy). If you only have a
laptop, then a good USB soundcard is the only feasible option. A USB
soundcard would also work well with a desktop PC, of course, so it's
the most flexible solution.
