hey Phisherman....awful generous of you. And actually....i think i MAY have the capacity to listen to MKV files. Let me share somethign i was reading on the web:
from www.howtogeek.com/200736/what-...and-how-do-you-play- them/
Our favorite choice for playing MKV files is VLC media player—mostly because it has built-in support and doesn’t require that you install anything else. Downloading and installing the program is easy if you follow these directions. Begin by navigating to the official download page at videolan.org. Beware of going anywhere else, because a lot of crapware vendors have fake VLC download sites.
Simply run the downloaded file to install VLC. The entire installation process should take no more than two or three minutes.
After the install is done, you’ll be able to watch any of your MKV files. Note that, while VLC does associate itself with all supported video and audio formats during the installation—including MKV—it does not register itself as the default app for those file types.
To watch an MKV file using VLC, right-click the MKV file, point to “Open With,” and then choose “VLC Media Player.”
....then they go on an give a few more details. blah, blah blah...more great details on how to do it. the POINT in my pasting their primer is, yes, I actually ALREADY have VLC media player on my computer. So, if you forwarded the MKV file to me.....since this primer is telling me that VLC player CAN play MKV files......I should be good to play it, using my VLC app on my computer....is that CORRECT?
