Well ... theoretically, this would work, provided that you "demodulator" is
actually a standard cable box sans descrambling circuit and it doesn't filter
out scrambled channels and replace them with a blue screen or a prevue channel.

Also, your cable system would have to have a premium channel on chanel 3 for
this to work.  The programming information for scrambled channels actually has
a channel number encoded in it, so your scrambled channel, remodulated to 
channel three still contains the descrambling info for the original channel.

Thus the Jerrold 450 will happily tune in channel 3 (scrambled picture and all)
while descrambling the non-existant premium channel.

BTW, feeding a scrambled channel into a cable box set to a non-scrambled will
not descramble the channel.  Unscrambled channels are broadcast in the clear
and the cable box knows not to engage its descambling circuits on those
channels.

The correct answer is 3.

Scrambled channels in the Jerrold system, are transmittted with a 'bit
stream' enoded in the Vertical Blanking Interval (the black horizontal
line you see when you turn the vertical hold control).  Premium
channels each have their own bit-stream, and all basic channels share
a bit-stream.    The decodr is addressable to one of several 'tiers'
of service.  

Level one might be all unscrmbled channels only
Level two might be all basic channels
Level three might be basic and HBO
Level 4 ... basic and Showtime.. etc

So, if you take a converter and send your HBO down to channel 3, where
a scrambled basic channel is, the cable company decoder will see a
bit-stream that is fron HBO, and will turn off.  These decoders do not
know what channel they are tuned to.  All they do is read the data
stream sent along with the signal of each channel, compare it to the
tier of service that the cable company has told them to operate at,
and respond appropriately.  This is true of most addressable decoders.
In the case of the Jerrold 450, the default is to shut down when it
sees a signal that it is not authorized to receive.

Sorry.

PS VCR's canot be used as converters for decoding.  They have complete
video circuts in them that wont pass raw signals to decoders.

Forget it.  Believe it or not, unless you pay the cable company to rent one
of their remote controls, they *disable* the remote feature of your box.  They
can control that just like they can turn scrambled channels on and off.

Most cable companies that use Jerrold and Scientific Atlanta boxes use the
standard tri-mode scrambling method, a variation of inband gated sync.

Want to bet on whether the color temp can be adjusted all the way down? My only
experience is with the Proton, and it's lowest temp is still too warm.

You would think that if they are going to the trouble of providing settable
color temperature they would put the correct temperature in the available
settings. (Anyone know what the HOT setting from Proton is? Must be about
9000 K.)

Maybe Mitsubishi will really do it right, but even if they do, I'll never be
able to afford it, I'm afraid.

Not really, because the line-doubler technology is always advancing, and it's
hard to guess in advance just how much the customer is willing to spend on
the projector vs the doubler, so...

"Projection IDTV" almost always takes the form of a data-grade (VGA or better)
projector and an outboard line doubler.  In general, you can expect to spend
about the same dollars on each of the two components.

Don't bother getting a cheap (under $5K) line doubler for a cheap LCD
projector, since they provide previous-field-retention for free, and their
response time is so slow that any sophisticated processing is wasted.

Hmm..I may be confusing my terms, but I always understood
video dub was to place video "over" existing audio material

I think it's a matter of faith here. Unless you want to buy another

nothing happens with your D701. I've had mine for about 6 months now

may or may not be lucky. It could break or that glitch that is

The point of fractal compression is that it doesn't exactly store the data
per se, it stores a function, a description of how to recreate the data,
that is how it can perform such serious compression.  The whole field is
very exciting and I have no doubt that it will yield interesting results
making all present video compression systems seem very bulky indeed.

Now, I know the English (PAL) answer to this one....  S-VHS (LP) ie 360mins
recording time is better than VHS (SP) 180 mins recording time.  But with a
slight increase in price.  Now for NTSC, SVHS(EP) 360mins is probobly slightly
better than VHS(SP) 120 mins.  But for a slight decrease in price.

Now, NTSC EP on SVHSmay be a little less durable than than VHS SP and it won't
be as easy to track into on a differnt VCR, so it may be best too use SVHS EP
for not so important recordings.

From what I have seen and experienced with my own Kloss Novabeam 100,
the blue is subject to blooming at a much lower level than the
red or green.  If you are not afraid to open up the set, try adjusting
the blue drive control WAY down and see if that brings it into
focus.  Try to get a service manual if possible; it makes the job
of converging the set MUCH easier.

I am having a strange problem with my Mitsubishi VCR.  It is about 4 years
old, but has never given me any other trouble before this.  

I started taping all of my temporary taping on T-160 Scotch tape about a
year ago so that I could get more on the tape.  Since I might have to go a
while before I get a chance to sit down and check out the shows, I rotate
through about 3 tapes.  I do most of my permenant taping on Scotch T-120.
When I went back to watch something on the T-120 recently, I noticed that
the quality was horrible, so bad that I could barely make out what was
going on.  I thought the heads needed cleaning and used one of those
commercial cleaning tapes, but it didn't help or hurt the quality.  When I
started testing some old and new tapes I got the following results:
T-160s look fine but not great, T-120 are terrible (Sony's and Scotch),
tapes that I taped long ago are fine but a little grainy.

Does anyone have an idea of what might be wrong before I go to a VCR
repair place and have the tell me it is the power supply and costs more
then the VCR to fix?

There is a direct tradeoff between the gain of the screen and viewing
angle.  Currently, screens being installed in higher-end home theatre
applications have a gain of about 1.5.  There is some pressure to reduce
