I have a TiVo (DirecTiVo) which is several years old. It has a few
hacks but nothing major. I've been watching these posts for several
months but need some practical advice and experience. I am interested
in MythTV using Comcast as my providor. We have virtually no Over the
Air signals where I live and so don't even own a TV antenna.
First. my "must have" features (from TiVo)
1) Season Pass (record all "new" instances of a particular program)
2) Program Extract (standard VCR functionality of recording a show
to removable media)
3) Web Control (a web interface)
4) Ease of use (it's an appliance)
Previous posts suggest that none of this will be a problem.
Now the real problem, caused by the cable companies and the changing
video formats. There seem to be two main decision points. Analog or
Digital and Standard or HDTV. These questions are specific to Comcast
although they should be the same for any cable company.
My TV is capable of 1080i and if I'm going to "upgrade" then I'd
probably like to enable HDTV. I really dislike the "cable boxes". I
believe that means I'm watching only analog signals and certainly no HDTV.
If I get one of the "listed" HD tuners will I get all of the Comcast
HDTV content or only the "local" stations which they are passing
through? I'm very confused about which stations I can and can't pick up
and in which quality. For that matter someday I think they're going to
discontinue analog. What will be the impact to PVR's at that point? I
don't want to even think about the broadcast flag.
Who'd have ever thought they'd make it so darned hard just to pick up TV
signals (with commercials). I guess fair use is about dead, but I
One disadvantage of the HDTV cards is that they have no on card
compression. HDTV is apparently digital already and so is already
MPEG-2 encoded, thus there is no need for on card encoding. What about
all of the "standard" channels? Can the HDTV cards do analog and
digital (or is it even needed based on the questions above)? Also, HDTV
playback apparently requires a rather substantial machine, not just some
old junker lying around, so, is it worth it?
Any advice and experiences would be greatly appreciated. What channels
can I expect to receive? Analog or Digital, STD or HDTV?
