Sorry, I haven't managed to read through 10 pages.
I love the idea of the program. However, going through the process of making links and copying the start movie file to every folder just seems like a bit of work. I would suggest a "pre" script that scans the hard drives for video_ts files, copies the file there then creates a link in Movies.
For me, I have been using Handbrake. I have about 900 movies. At 4-9GB, we are talking 3.6TB to 8.1 Terrabytes. Oops.
So, while I copy my movies for backup (small children), I also rip them to h.264. I then put those into a folder on my external drive(s) and create aliases to those folders into my Movies directory.
I have a compiled version of Handbrake that includes HBTest, which is the command line version. I then created a perl script that encodes the files (works for video_ts, iso and img files), moves the original to a "Done" folder (so I can verify the conversion went well).
This basically allows my EyeHome to use them and my Macs.
As I just got my projector and settled into the new house, my intel Mini is becoming the new media center system.
So, my thought above for having a script create the entries may help some out. I personally would love the full DVD (and the corresponding audio quality), but I don't want to spend the $$$ on so much space. Well that, and I would spend a month copying all the dvds again (even with 4 drives).
BTW, if anyone would like my script, I wrote it in perl. I am happy to share it.
