I tried out SubscribeTV tonight. The guide for the US channels was not working so I emailed for support. The guy gave me the standard and clear your data and cache response. I did so and it still didn't work. I responded with a screenshot of the guide showing no data.

I was ignored so I posted a short review on IPTV. The guy responded calling me a troll and cursing at me. I don't understand why he was so angry but that's the response that I got. Needless to say I would suggest avoiding SubscribeTV.
