Need to edit teaching video, decrypt DVD - Is this good software?

[NEOooo2]

Currently I need to edit teaching video for my student. So I'm looking for some tools to edit, I have tried Handbrake,but it just cannot do anything with most DVDs unless you have decryption software installed. Just now I found this one : http://www.videoconverterfactory.com...deo-converter/
So my question is : Is it worth to purchase ? Who else have tried this tool ? Appreciate for you advice !

That's not going to avoid decryption either.

Copy protection has to be decrypted and reorganized into readable MPEG video files. The most popular apps for this are DVDFab (old now and not updated for newer decryption schemes, but might still work on some common older schemes), DVDFab HD Decrypter for both SD and HD sources, AnyDVD (also older), and AnyDVD-HD.

Handbrake is not an editor. It's an encoder. It's really really really a bad idea to re-encode lossy encoded video, and formats such as MPEG, BD, AVCHD, etc., are final delivery formats, not editing formats. MPEG should be edited with cut and join operations using frame-specific smart rendering editors. TMPGenc Smart Renderer is pretty good at it and contains a few extra features such as transitions and simple audio filters. Re-encoding DVD is a no-no. Lossy DVD encoding isn't like ZIP or RAR. Re-encoding lowers quality. There's no way around it.

None of these decrypters or smart renderers are free. The creators spend plenty for decoder/encoder licensing that makes their apps useable. There are a few freebies around for edits, but most don't smart-render and/or have no useful features except simple cut and join on key frames only.

Handbrake is a poor app for editing. It re-encodes everything. It's OK for what it does, but it's unsuitable for your purpose.

Though "old" DVD Decrypter still works on probably 95%+ of discs.

It usually just big-name blockbuster/Hollywood movies have the hard-to-crack protections. And honestly, almost none of them are worth watching anyway. When I do like a movie, I tend to buy it used or new from Amazon. It's uncommon for a HTF/OOP/rare disc to have the newer protections. In fact, the only one I can think of offhand is the 4th wave of the Disney Treasures. I own the original tins, but wanted drive backups. Pressed DVD actually dies much faster that DVD-R/+R, and quite a few of mine have gone bad over the years. One of my 1st wave discs had gone bad, and it was a real PITA to replace.
