I bought the Ceton InfiniTV 6 Eth a couple days ago and I'm pretty disappointed with this thing so far. It takes 5 to 10 seconds to tune into a channel and on Windows 7 it seems I can only use 4 of the tuners. What I do like about the InfiniTV is that I am able to watch all of my cable channels, including HBO. I was considering the SD HDHomeRun Prime, but when I click on the supported channel list for my cable provider is only shows about 50 channels. It's a CableCard box, is the channel selection really that limited? I wonder why the Ceton can get all the channels and this can't? If I can get all the channels on the HDHomeRun Prime then I'll probably order this, because people say it tunes channel much faster than the Ceton. I guess if both of these boxes suck, I might just need to buy a TiVo. It'll still be cheaper than the outrageous fees my cable company charges for cable boxes and DVR service. I could live with the $15 a month fee, though I'm puzzled why TiVo charges a monthly fee on the TiVo Mini extender box too.
