I usually never use the NexDef plug-in as it has always led to more glitches and lag than it is worth to me (plus it didn’t work on Win7 x64 systems last year). Still, I did track my Internet usage for a while two years ago when AT&T then threatened to introduce usage caps (during the Reno, NV and Beaumont, TX trial runs). Even when using MLB.TV almost daily for Cubs games at the max non-NexDef bitrate and doing my other normal Internet tasks, I rarely went over 60GB of downloading per month. Since I have WGN America access now, my MLB.TV usage is reduced, so I am not expecting any cap issues immediately. That does not mean I will take this policy change lightly, but with Charter having a similar cap, there is not much I can do about it currently.

Once I get signed up for MLB.TV this year (waiting to see if any discounts appear) and high bitrate games are transmitted again (may not until the season starts), I will track the average download usage for a game stream. I expect that if you heavily use Netflix, Vudu, or other services like that along with MLB.TV, you might go over your cap limit (especially with the lower cap for DSL usage). Most normal users should be fine for the short term.
