Does anyone have a theory on what kind of broadband speed will be required for good picture/sound quality on Sky Angel IPTV? Their website says 1.5MBps. To subscribe to their IPTV service, I will need to upgrade my dsl from 768K to 3.0 MBps but I'm wondering if that will be enough. Anything more than that would require getting a cable internet modem with accompanying tv package. Any comments/suggestions appreciated. Thanks.
