MediaPortal Version: 0.2.2.0
MediaPortal Skin: Blue Two or Project Mayhem
Windows Version: XP SP2
CPU Type: AMD XP 3000+
HDD: Western Digital 40Gig
Memory: PC3200 1 GB
Motherboard: ASUS A7n8x
Motherboard Chipset: Nvidia Nforce 2
Motherboard Bios:
Video Card: Geforce 7600GS
Video Card Driver: 91.47
Sound Card: Sound Blaster Audigy Platinum
Sound Card AC3: coax out (stereo mini)
Sound Card Driver:
1. TV Card: Hauppauge HVR-1600
1. TV Card Type: ATSC/ANALOG
1. TV Card Driver:
MPEG2 Video Codec: MPV
MPEG2 Audio Codec: MPA
Satelite/CableTV Provider: Dish Network
HTPC Case: Coolermaster Cavalier T02
Cooling: Thermalright Si-97, Nexus Fans
Power Supply: proprietary to case
Remote: streamzap, hauppauge
TV: Samsung HCL652W
TV - HTPC Connection: Component

I'm a bit stuck here, and wanted to post a question to see if anyone had an idea that might be a bit deeper than what I've tried.

I've been running into a problem with getting the TV to work through my svid port on my capture card. After driver reinstalls, MP reinstalls, and such, I started to dig deeper and really figure out what was going on. At the suggestion of another member during a PM convo, I installed DScaler, as the Dscaler software works with graphedit while watching TV, whereas the WinTV software from hauppauge does not.

Dscaler works just fine, and in fact produces the same graph that is in the CaptureCardDefinitions.xml file. I ran graph edit against both MP and Dscaler to see the differences... They're both the same at the beginning:
Hauppauge 418 Tv Tuner->Hauppauge 418 crossbar->Hauppauge 418 capture...

From here they separate into two different directions, because DScaler sends the video to the screen, and MP wants to encode it to record to the HD. MP then sends the capture "656" pin to the Hauppauge 418 Encoder, which is then supposed to go to the Mpeg-2 Demultiplexer. This doesn't work. I figured this out from the infamous error message in the MP log file:

FAILED to connect encoder->mpeg2 demuxer

After fiddling around a bit more, this is what I've found will fix it. If I boot up MP, and open graph edit and connect to the MP graph while MP is on the home screen, I will get all of the filters, and just like MP says, the encoder and MPG2 demultiplexer are not connected. If I MANUALLY connect them at this point, it works, and I can go watch TV.

I'm just not understanding why MP will not connect the Encoder and Demultiplexer on boot, although I can manually go and drag the pins together. Any thoughts would be awesome. Thanks you guys.

Man, this is really bugging me. It still plagues me, and I"ve tried everything I can think of.

I thought it might be a problem with the hauppauge encoder settings, but I managed to go through most of them (by opening the settings in graph edit) and changing things to see if I could get it to work - no go.

The thing that really bugs me is that I can manually connect the encoder to the mpeg2 demux after mediaportal starts, but it won't do it by itself, it throws that error.

is there ANYONE who can give me another thought?
