I am doing some experiments trying to watch my Channels content while VPNing into my home network. I only have 20Mbs upload at the house (I am going to switch to Metronet to improve that) and if I try to watch live TV it just can't handle it and it plays for a second and then buffers for 3 seconds and repetes. But if I watch a recording from my channels DVR, it buffers a little in the beginning and then runs ok. Also, if I chose to watch a TVE stream, it works ok.
So, does watching a program live use more data than watching a recording?
