I used to watch it through various internet browsers on the computer and had similar issues. Often, I could never get to the end of a program. It would lock up often, might recover a couple times, but eventually would have to be restarted from the beginning. I checked with half dozen friends who tried watching it in browsers, and all had the same problem.

Like NokieHokie mentioned, it's available on Roku and some other media players. I installed the WatchESPN app on Roku about a year ago, and it's worked great. I've probably watched 100+ programs on it and had maybe 2 hangup. Even then, it's not much of a headache. Fast forwarding or rewinding is very stable, quick, and has hardly any buffering.

For use on PCs with Windows 10 (actually anything later than 8.1). There is a WatchESPN app also. I haven't tried it, but wonder if it would be be stable also.
