I don't mean to make anyone upset, but HD Dish Tivo is the only sub 1-2
year way, if ever. We can dream about hardware DVI encoders for up to
1080i but they will all be illegal. The July 1st HD copy protection, DRM,
and DCMA make it so the media industry at a moments notice can change
any sold or selling consumer electronic devices' status on being legal.
If someone finds a way to get the data over USB, Firewire, DVI, or
anything in an "un-authorized" way the HD copy protection laws allow the
media insdustry to simply submit a notice to the FCC about a "change"
and that is all it takes to end you from doing what you want, without
having to then worry about using an illegal device. This is why the HD
copy protection laws are so bad.
HD Tivo's are DRM certified and also include specialized hardware or
software for dealing with dish or satellite encryption, which would be
extremely rare for a HD tuner for a computer and also would be illegal.
This is why your best option may end up being an HD Tivo, as much as I
don't like it, but I also don't have the resources to fight this. - So
I'm telling you what I see as options. :-/ Supporting EFF is a good way
though to support the fight against things like this.
Tivo is actually fighting for some things that could benefit us, such as
getting permission to send shows to a select list of friends. If this
applies for HD, it could contradict the HD copy protection, unless it
will only be allowed through a network that supports DRM.
Also to note,
I'm not sure the status on the following, but I know the MPAA was trying
to get a mandate passed that required all HD equipment to auto-check for
connections to blacklisted equipment and if connected to one it is to
shut down output. This is unfair, but the MPAA can buy that monopoly.
The other great read is on the MPAA trying to make all Analog to Digital
converters require supporting DRM. This is obsurd, but it's our movie
ticket prices at work. I personally like the jokes about copy
protecting earthquake signals or not being able to record a birthday in
a park because some kid drives by in a car blasting his Copyrighted music,
or hearing aids going quiet because of copyrighted speaches or phrases.

They're about $30k for encoders. DVI would not be bad, but you are
re-encoding from a lossy format, but I doubt you would notice any change

I answered this out of order, so it's above.

Not yet, they're working on it though. I think within 6months to a year
we will see this.
