If it came from an unknown src, yes of course. But this was from my son, 
who is pretty savvy, and would not knowingly send me anything malicious.  
We once spent several hours trying to hack into each others computers. 
Despite his was a vista at the time, he had it locked up pretty good. He 
of course had no better luck getting into mine.

Pretty much but I'll check come local daylight...

Changed things around, discovered that mplayer-gui, not mplayer, was 
required to even get it listed as a choice, installed some more codecs, 
but one demanded the removal of 90% of the system. Canceled that one. 
Thats an aptitude trick. I have never, regardless of package format, 
seen anything that could tear down a perfectly working system like 
aptitude can. But it still times out. Sigh.

Yes. And somewhat locked to it because that is the distro the current 
LinuxCNC is written to run on. I do have one oddball install, jessie on 
an r-py-3b, running an 11"x54" Sheldon lathe thats about 70 yo.

Someone mentioned kplayer, but I'm not running KDE, using TDE R14.0.5 
which apparently doesn't have that. Theres been so many wrappers around 
mplayer its confusing.

Thanks.
