2 TV Tuners |
|
|
Are there any DVD HDD recorders with 2 TV tuners so you can record 2
TV programs on 2 different channels at the same time?

But the hard drive is only capable of recording one program at a time.
In time when the price drops you could own 2 DVD recorders, just like
people owning more than one VHS recorder then 2 programs coulfd be
recorded at once.

No, the hard drive is definitely capable of recording multiple
programs simultaneously. I don't have a link handy, but I've read
reviews of PC's with at least three Hauppauge dual-tuner cards
installed, recording 6 standard-def TV programs at the same time.
My guess is that manufacturers aren't willing to increase the cost to
cover a dual tuner setup when their market research indicates not
enough people would pay extra for the feature. Personally, I'd love to
have a quad-tuner model if they offered it.

Why do you think that?
The hard drive in your computer is recording all sorts of different
things from different processes running simultaneously. It's called
multitasking. |

Does anyone else make dual tuner cards?

I don't have cable so I am limited to broadcast shows.

I can get a Panasonic 4-head VCR for $50. I have two VCRs of different
vintages now but one is crapping out from excessive use. So I can
replace it with one Panasonic for $50.
I would be willing to pay up to $100 for a dual tuner HDD recorder.
They can keep the DVD - I have enough of those around here to start a
recording studio.
I am beginning to think the time has come to build a computer to do
the task. I assume tuner card come with scheduler software or else it
is pretty much useless.
Has anyone been involved in such a project? |

Quite. I've got a PC with a USB VisionDTV connected as well as a Nebula
DigiTV PCI card. The latest S/W for the latter allows more than one program
to be recorded if they are on the same multiplex (as well as supporting
multiple tuners, and they have a dual-tuner USB device coming soon). I have
recorded three programs simultaneously, one from the VisionDTV and two from
the DigiTV, without problem. Even the 5400rpm drives typically used in STBs
would have no problem with the data rates involved.

Not me, (yet), but I'm leaning toward the Snapstream "Medusa" project
mentioned at these links. This is what I was thinking of when I
replied above but didn't have links handy.

haven't heard of any that allow you to record two channels at once.
there are however ones with 2 tuners that allow you to record one
channel and watch another at the same time

You do not need 2 tuners to do that. One tuner feeds to the recorder
and the signal then goes to the TV which displays the second program.
VCRs allow you to record one channel and watch another but there is
only one tuner in them. |

Yes the Topfield PVR5000 series is capable of recording 2 different digital
TV channels and playing back at previously recorded program at the same
time.

Because when I'm recording a TV program to the hard drive, I can't do
any other recording on my DVD recorder. It would be nise to be able to
copy a program from the hard drive to a DVD disc while recording a TV
program to the hard drive. It would be also nise to be able to record
from an external souce such as a video camera to the hard drive while
recording a TV program to the hard drive, but this is not possible.
And the reason must be that in the case of my DVD recorder and it's
likely to be other DVD recorders is that they are only capable of
recording one program at a time to the hard drive.

If I record from my video camera to my computer hartd drive then try
to move a group of programs from one partition to another partition on
my hard drive then I get drop outs in the picture as there is no
longer that constant stream of data to the hard drive.

:
motorola DVR-6412, as distributed by comcast cable. two tuners.
use it all the time.
it may not be available as a commercial product, since it requires
access to a guide system to program in the tivo fashion, and comcast
provides that. unfortunately, the software was done by m$oft, and is
as clunky as all m$oft products.

What you have just described is a limitation of the program that
controls the DVD Recorder, not a limitation of the hard drive itself.

Again, that's a problem with the program that controls your recorder,
not a limitation of the hard drive.
With a multi-tasking disk operating system, you would be able to do
multiple tasks all involving the hard drive - like UNIX, Windows NT or
an old IBM mainframe system does. Even a task switcher like Win9X or
Win3X could simulate multitasking and let you do the things you
described.
The hard disk is fully capable of handling multiple simultaneous
requests. |
