If you just have extended basic, you can probably return the box to Comcast and run the cable directly into your capture card. (You can test this by running it straight into your TV before buying a card or sending the box back if you're sane enough to not just take my word for it.) As long as it's not digital, the only channels that need to be descrambled are generally the premium channels - HBO, Cinemax, etc. The basic stations are normally sent in the clear. > I want to be able to watch tv while recording a different channel.

If you want to watch one thing on live TV (as opposed to watching a previously-recorded program) while recording something else, then, yes, you would need two tuners. However, once you give myth a try, you may find yourself never wanting to watch live TV again... Also, there are dual-tuner cards out there, such as the Hauppage PVR-500 (which I currently use, although only one tuner is working for me), so you don't necessarily need two cards. When I bought mine, newegg.com was selling the dual-tuner PVR-500 for only $10 more than the single-tuner PVR-150, so I see no reason not to get one. > My question is if I just > split the cable from the cablebox, is there any way to record something and > simultaneously watch a different channel or do I have to have two cable > boxes for this? Each cable box only has one tuner (there are some exceptions, but the only ones I know of have DVRs built-in, so you're not likely to be using mythtv with them) and, if you run your signal through the cable box, you have to use its tuner, not your own (which will generally be locked on channel 3 or 4 to match the cable box's output). So, if you run your video through the cable box, then 1 box = 1 tuner = 1 show at a time, regardless of how many tuners your mythtv system may have. But, like I said above, you probably don't need the cable box anyhow. (Even if you do have some scrambled premium channels, you could set them to only be recorded on a specific tuner which goes through the cable box while having a direct cable line into the other tuner to record non-scrambled channels.) -- The freedoms that we enjoy presently are the most important victories of the White Hats over the past several millennia, and it is vitally important that we don't give them up now, only because we are frightened. - Eolake Stobblehouse (http://stobblehouse.com/text/battle.html)
