New Comcast Upgrade better?

Looking at a video being presented by the Comcast people relating to the new move to digital, I was surprised to find out that even though I have cable I would still need to add a digital convertor box to at least 2 of my TV's despite the ads saying otherwise on regular channels. I was lucky to catch the video on a Digital only channel while scanning a friends TV for more channels something that I would not know by just seeing cable analog channels I receive. So I called customer support to ask about the convertors. Lucky for me (and other customers of Comcast) the cable company is offering 2 free convertors per household but I was intised to get even a better setup, faster Internet package & cable channel package that included HBO for a low rate to last only a year. It would cost me (so they said) less than what I pay now for a lesser setup so I took it hoping to see finally some real speed and performance on the Internet but that did not happen. Todays tests showed a whopping .168mbps or less then my other package when I had expected something close to the promised speed of 12Mbps. I am still convinced that my area as a whole had an issue that the Comcast people fail to recognize or even fix. I am still waiting for a responsible individual from comcast to explain previous issue causes but yet to get a response. I think I will even have to wait more fir the current issue which would not surprise me to hear them say it is caused by a picture frame in my home or some other ridiculouse explaination. I await to hear from someone not too chicken to explain cause and I hope fix to this issue, I will not hold my breath. I will continue to monitor this into it is fixed and explained.
