I'm having the same issues as the other posters, i.e. videos that played without a problem prior to the last major update now will only run for 5 to 10 seconds before having to buffer. Additionally, some formats that played before now instantly crash once they have buffered (e.g. .TS). Nothing has changed in my setup except the Videostream update, and following all your suggestions, as with other posters, has made no difference. I have 5GHz wifi and nobody else is using my network. My belief is that your developers somehow broke or messed up your transcoder.
