I have a ViewStar cable box with baseband video and mono audio outputs.
I'd like to add stereo outputs to the unit through an MTS decoder chip.
I've checked a couple data books, but can't find any with what I'm looking
for.  Ideally it would be something that would take the audio IF (which
hopefully is available inside the ViewStar box somewhere!) as input, and
the output of the IC would just be simple line-level audio (in stereo!).

Or:
   Audio
    IF       ::::::::::::::--->--- L audio output
 ---->-------: Mystery IC :       
 from tuner  ::::::::::::::--->--- R audio output

[I'm assuming that by the time the mono audio is generated, the MTS
information is lost.  If not, then something that would convert line-
level audio to MTS stereo would be great, too.]

In the data books I've looked at, they all seem to have outputs that then
require the signals be passed through an FM decoder, or some other
extra converter, etc.  Are there any "simple" MTS decoder chips available?
If not, a recommended "combo" would be fine.

Any info would be appreciated... I will summarize replies to the net, and
if I get the circuit working with the ViewStar, I'll post instructions so
others can do the mod -- I know there's a BIG demand for baseband video
and MTS stereo cable boxes!  (Or alternatively, a device which takes
"Channel 3 Input" and provides baseband video/stereo audio outputs.  I
asked about this on the net a couple months ago and everybody said "buy
a VCR".  I have a VCR, I don't have room for another one [even if it is
broken!]  I just want a small, low-cost "black box" that hangs off the
back of my current CATV converter so I can use the 'Aux' channel on my VCR
[read: the video input on the back] instead of having it tuned to channel
3 all the time!!  Since there were no other suggestions there, this is my 
next idea.)

So... any info on a nice, easy-to-use MTS decoder chip would be 
appreciated!  Thanks.
