Aiseesoft Total Video Converter is one I didn't have, so I can't say what's new & what isn't. A quick look at the file versions & dates in the program's folder suggests if there's anything new or tweaked it in the editing end of things -- nothing in ffmpeg or QT etc. is new. As someone else noted, this doesn't have 3D capabilities, but then I'm not at all sure that many people use those anyway -- in the Plat version it'll use the standard 2D movie on a 3D Blu-Ray, & then could use the 3D data in the accompanying file on the Blu-Ray disc to create a permanently 3D video, in your choice of 3D format [you'd use whatever format was compatible with your display].
Several of the Aiseesoft apps understand & will import DVD & Blu-Ray discs -- Total Video Converter will accept the video files, but it won't understand the disc layout. What that means is you'll want to extract the audio/video from a DRM-free DVD & feed that to the software; DVD Shrink will copy a DVD's several VOB files to a single VOB file that'll work. Blu-Rays may or may not use more than one file for video -- if/when needed the Tsmuxer Beta should work OK if there's more than one. [You could probably merge DVD VOB files in the converter, but it only takes a minute or two to copy with Shrink, & then you don't have any added hassles or possible glitches in the converter or anything. If you've got Blu-Ray video spread across files, again you might merge or join them in the converter, but Tsmuxer will read the play list (you can't), making sure they're in the right order.]
Of course the big question a lot of folks will ask is: "Why grab another converter?" If you've already got one or more that you use a lot & are happy with, the choice is more a coin toss. If you don't do a lot of conversions in one or a few apps already, I'd lean towards installing Aiseesoft's Total Video Converter -- here's why...
Not long ago I ran a bunch of converters, encoders, & editors through their paces -- I needed to know how Nero 2014 & Roxio NXT did, having picked them both up dirt cheap. Performance of the [AFAIK] China-based software with ffmpeg had really improved at HD frame sizes [where they used to be weak], but glitches were unfortunately common. Quite often what I set was not what I got, or I had to restart the app to make settings stick, or check boxes &/or settings made no difference to the result. And that sort of thing varied with the software version -- where one version might be trouble free, the next might have several problems. Long story short, I now do a quick, short, test conversion before I do a full transcode, checking the result 1st with MediaInfo, & then if the file agrees with the settings I made, I'll check it with a couple of players. If/when one app comes up short, I'll try the next. It's a small PITA, but I don't use these converters a lot, version updates are frequent, and the source video is different each time, so I've found it necessary, e.g. one recent project meant trying 6 apps before one got it right.
Aiseesoft Total Video Converter takes up about 100 MB of disk space -- if you work with video, where lossless HD can take up hundreds of GB, with AVC versions taking up around 20 - 25, that's no big deal in comparison, so apologies if it bothers anyone when I treat 100 MB as if it were nothing. You get added folders in My Documents, ProgramData, & C:\Users\ [UserName]\ AppData\ Local\ . The registry gets a new key for the program's name, an uninstall key, & unavoidably several QT cache keys/values [any time software uses QT you get several Trolltech entries].
