How to make Pinnacle PCTV Stereo to work on Windows Media En |
|
|
I run not less than 20 Pinnacle PCTV cards (Studio, Rave, Pro…) for my
broadcast monitoring business based in Mexico City. I use Windows Media
Encoder 9 based applications to do so, often with two or three PCTV cards in
the same box, with good results.
I recently bought five more cards of the new model, PCTV Stereo. I found
Pinnacle changed the TV chips, from BT8x8 to Philips SAA713x and I was
excited, since I know these chips support direct audio capture without the
need of an additional audio card.
Unfortunately, although Pinnacle claims PCTV Stereo drivers are “Full
WDM/BDA compliant driver, WHQL certified” I cannot make the cards run on
Windows Media Encoder 9. (Brand new Win XP Pro 2ghz PCs with service pack2
and all OS updates) I Installed the XP SP2 Driver update Pinnacle offers for
this card (2xhybrid.sys V 3.1.3.1.15), and PCTV Vision application works
fine. But in Windows Media Encoder, all I get is a green screen; no matter
if the input is Composite, Svideo or Tunner, no matter the zillions of
adjustments I do, even starting all over (From different hard-disk formatted,
different CPU and MoBo PCs) the result is the same: Green screen. Audio from
TV captures fine in every channel, but no video at all.
I have lots of expertise using WMEnc on PCTV cards. For example in latter
BT8x8 versions with V 5.5 drivers, you have to specify YUY2 on pixel format,
otherwise you get a blueish image. The bad experience with PCTV Stereo on WME
is that no matter how many adjustments you do, or not to make any adjustment
at all, using a fresh installation on different machines, the video is always
a green screen.
The most intriguing part is that other programs that work “without any
problems on TV Cards that have a compatible WDM Driver installed” like this
Crhis-TV PVR software (http://www.chris-tv.com/cards.html ) run perfectly on
the PCTV Stereo card with the Pinnacle drivers mentioned; even the audio part.
As usual with BT8x8 chip based cards, I looked for alternative drivers for
the Philips SAA713x chip. I found several ones for cards of different
vendors, based on “reference Philips driver” (cap7134.sys, phvtune.sys) and,
amazingly, managed to get PCTV Stereo video working in Windows Media Encoder
(Some Fly TV/Prime versions, and also an Asus TV Tuner one) but
unfortunately, the Audio part does not appear in the list of devices. Also,
you have to switch to Composite Video source to get TV Tuner signal, and
select TV Tuner to get the Composite input)
So, as you can see, I have tried everything in my hand to have this new
SAA7133HL based PTCV Stereo card working in the most obvious WDM application,
Windows Media Encoder, and all I get is a green screen and several new, not
returnable cards in their boxes.
So my only question is: How can you make PCTV Stereo card to work on Windows
Media Encoder as it is supposed to work since its drivers are “Full WDM/BDA
compliant driver, WHQL certified”??
