VDH has been great up until the 7.3.9 release. It then started behaving bad, as in starting, but never completing video downloads in linux. I tracked this stopping to a build with a library(GLIBC) version that is ahead of many linux distributions. Researching in Google, VDH personnel are claiming that it is not their problem and are doing nothing. GLIBCs normally work if the program build is on a lower version than the distribution. It seems like VDH only needs to build using an earlier GLIBC version.
4/17/20 update -- I checked a windows version and I get the same strange behavior of hanging in the middle of a download forever. Manually stopping it in windows, unlike linux, does not result in any error message.
5/9/20 Loaded up Coapp 1.5 and tested again. Did not work any better. Still getting the same errors(below) and only ".parts" of warying sizes.
Errors:
