Dear GetNexTV.com,
Kudos to you for fixing the "frozen picture" issue. Indeed I have noticed that it was no longer an issue for me starting last evening (Wed.).
Regarding the "time shifting", I would hope that you are only considering adding the time shifted channels in addition to showing them "live", as there are many instances when it is desireable to watch the channels live, e.g., news, sporting events, etc.
In any case, keep up the good work and many thanks for listening and being responsive to subscriber feedback.
Cheers
