Installation is MESSY. Like many players Zoom Player uses open source & free code, but rather than incorporating that code into their own software, here it's installed individually. You get: 3DYD Youtube Source [ ys.3dyd[.]com] -- Bass Audio Decoder [ free-codecs.com/download/bass_audio_source[.]htm ] -- DCoder Image Source [ dsp-worx[.]de ] -- DirectVobSub [ videohelp[.]com/software/VSFilter-DirectVobSub ] -- LAV Filters [ videohelp[.]com/software/LAV-Filters ] -- parts of the VLC player -- MadVR [ videohelp[.]com/software/madVR ] -- all in their individual folders, plus the Zoom Player folder, all in Program Files (x86)\. Then in ProgramData the Zoom Player folder holds all sorts of Direct X & assorted filters to handle various types of media files, with 726 files, 18 folders, taking up 244MB. In contrast the free & portable MPC-HC takes up ~58MB with 70 files, 6 folders, while portable VLC takes up ~141MB with 487 files, 52 folders.
I'm sure the Zoom Player MAX 19 does a decent job, but personally, I see zero incentives *for me* to switch to using it. For one, I prefer Not to install all those Direct X filters and such -- Windows media handling is a minefield, and it's much too easy to blow everything up, meaning you'll have problems from then on playing some stuff. The best known, most common way to do that is to install a bunch of DX filters & especially codec packs. Second, a player like MPC-HC is updated when a new version of something like the LAV Filters is released, but as a separate install I'd guess that updating is up to you. And 3rd, *for my purposes*, I don't see it offering anything special that I don't have right now.
For streaming TV there are now several apps in Windows Store, and with the exception of Max the most popular services seem to be covered -- I use Amazon's Prime Video app to watch Movies Anywhere titles we've bought. The Zoom Player MAX 19 like VLC can [maybe] play the Java menus & such on Blu-rays, after you install Java and make a few other mods -- I Googled for directions and instead found lots of complaints and requests for help getting it working. My copy of PowerDVD Ultra OTOH does that just fine. That said, I ran our Blu-rays through an app to simplify them, removing that Java stuff along with the HD audio etc., so VLC [including the Android version] plays them fine as-is, including on my wife's Kindle HD tablets. Zoom Player MAX 19 lets you use the LAV Filters & a special video renderer to get a better picture & sound, but so does MPC-HC. I don't do IPTV, but since the Zoom Player ad copy mentioned it, I looked it up... besides specialized players in Windows Store, VLC allegedly handles it just fine. I'm not sure about MPC-HC, but if you wanted to use the LAV Filters & a different rendering filter with VLC they're available separately and in portable versions too.
Long story short, sorry but while I'm sure it's a good player, I just don't see any reason to install the Zoom Player MAX 19.
