I did, though I forgot what font I used. It was pretty standard, and I sized them up to the original as much as possible.
"I realize the LD technology is analog, but what about the optical digital-out ports that were on many models, including my old Sony? Would those conceivably help with a higher-quality output?"
Yes. Think of it this way - if you were to record a song onto audio-cassette and onto the computer (as a .wav file), you would have much higher fidelity from the computer. Thye cassette takes the analog waveform and saves it in an analog format. The computer takes the analog waveform and saves it in a digital format, but it is still an analog waveform. This is why PCM soundtracks (on laserdisc or CD) are so large - it's the whole signal with no compression. In fact, PCM stands for "Pulse Code Modulation". Pulses (with their rise and fall) versus digital bits.
[EDIT] Bleh!
" I wonder if it would be possible to introduce a new laserdisc format that would not use those big ass 12" discs but instead the same size as DVD. Would it be possible to fit a similar amount of data onto one of those suckers as can be done with DVD´s?"
The new HD-DVDs hold between 30-50 GBs. An uncompressed capture of ANH is 200 GBs, so no.
