Re: [mythtv-users] Does mythtv support 1080p?

2006-01-11 Thread Michael Chmilar
The 1920x1200 computer monitors (like Apple's 23" Cinema monitor, or
others from Dell, Samsung, etc.) all do 1920x1200 over single-link
DVI. Why are TV's any different?

Re: [mythtv-users] DirecTV HD recording

2005-11-18 Thread Michael Chmilar
Thanks for the info.

It would be nice to connect the r5000hd receiver directly to the myth
box. Those tools would be useful to help figure out the demuxing of
the DirecTV streams, and making TS files.

I am still pursuing the DVHS emulation angle, though, as it looks
like less work than doing the direct connection.

Yes. A separate Windows PC must host the r5000hd. (The modded DirecTV
receiver outputs over USB2.) Unfortunately, the stream emanating from
the receiver is in DirecTV's proprietary format. To read directly off
the USB2 port, you have to reverse engineer the format. The r5000hd
crew has figured out how to convert DirecTV's format to a standard TS
stream, but their driver is only implemented on Windows.

This is essentially the same as the 169time and AVX-1. The AVX-1,
from what I understand, is pretty much a Windows PC.

Re: [mythtv-users] DirecTV HD recording

2005-11-18 Thread Michael Chmilar
There is also the r5000hd. http://www.r5000hd.com

Users who have had both the 169time and r5000hd consider the r5000hd
to be a far more reliable device. (There are two threads on the
r5000hd at http://www.avsforum.com, under the HDTV Recorders and
Players section. Lots of former 169time users. (There is also an
"upgrade" deal for 169time users).)

The r5000hd must be hosted on a Windows PC (much like the AVX1 for
the 169time). The Windows capture application for r5000hd has the
capability to output the data stream over firewire to a DVHS deck,
and it can be controlled (ie. tune to channel, start recording, stop)
by sending commands using telnet.

I have the r5000hd, and I have been tinkering with trying to capture
from firewire to MythTV. Basically, MythTV should emulate a DVHS
deck, and the r5000hd will happily stream the data. So far, I have
not been successful. I am currently educating myself on firewire and
iec61883 to see if I can get this going.

The problem seems to be that the r5000hd wants to engage in some
"chit-chat" with the DVHS deck (ie. there is a communication protocol
between a DVHS deck), which the Myth firewire module does not
provide. 

I have been successful in capturing from the r5000hd using the
VirtualDVHS application on Mac OS X. It can be done.

The firewire module in MythTV works with cable boxes. It appears that
the cable boxes continuously stream their data over firewire,
regardless of whether anyone is listening. The Myth module doesn't
engage in any chit-chat, it just starts grabbing the data.

The networks make their money by selling you (the audience) to
advertisers. If your recording contains the commercials, and you
don't have a mechanism for skipping or excising the commercials, then
watching or sharing your recording has not done any harm to the
networks. You are just helping them with additional distribution of
the advertisements.

As to the larger debate: U.S. copyright is a very sensible and
workable law (except for the "extensions" that media companies have
won). The problem with the broadcast flag is that it is far more
restrictive than copyright law. The broadcast flag prevents "fair
use" of media, which is legal according to copyright law.

As to the "cracking" of HDTV receivers that adhere to the broadcast
flag: This is where the DMCA comes into play. It is illegal to
circumvent a copyright protection mechanism. The protection mechanism
can be pathetically "weak" (such as the DVD CSS protection), but that
does not matter. While this does not prevent the underground from
distributing the information about cracking, it does stop
manufacturers and importers from selling a pre-cracked plug 'n' play
device to the masses, in the U.S.

The FCC broadcast flag proposal does mandate that devices be
reasonably secure against cracking, which probably means the
protection mechanism must be stronger than DVD CSS. It also stops an
HDTV card maker from adding a weak mechanism, and then "leaking" the
simple crack to the web.
