I guess those drivers simply don't work with the HVR-1255. I installed the HVR-1250 drivers anyway, and they installed fine, but previewing in VirtualDub via S-Video showed garbage/noise and no video. So I went to Device Manager and tried to locate the device drivers for it manually but it only listed "Hauppauge WinTV HVR-1250 (Model 79xxx, Hybrid ATSC/QAM)" and not "Hauppauge WinTV HVR-1255 (Model 22xxx, Hybrid ATSC/QAM)" as mine seems to be.

I uninstalled the Hauppauge drivers using HCWCLEAR but Windows could not find any drivers for it automatically. Hard Drives: 80 GB Intel X25-M G2, 1 TB Samsung HD103SIĬapture Card: Hauppauge WinTV HVR-1250 (in Device Manager it is listed as "Hauppauge WinTV HVR-1255 (Model 22xxx, Hybrid ATSC/QAM)")Ĭapture Software: VirtualDub 1.9.11 32-bitĭoes anyone else have this card? If so, could you please see if this is happening for you too?

I've tried the following to try and solve this issue, but the problem still persisted:ġ) Try the driver on the CD that came with the cardĤ) Try a different application (I tried iuVCS, Roxio Creator Pro 2011)ĥ) Try limiting the amount of RAM in msconfig to 3 GBĨ) Try some other source (I tried an Xbox 360 via composite connection)ĬPU: Intel Core 2 Duo E7400 OC'd to 3.8 GHz
What I think is happening is that shortly after the card is initialized some error occurs that causes the second S-Video source to turn red, and also causes the first S-Video source to "glitch" and get dim. Notice that in the second of the "glitch" screenshots, the bottom portion of the screen has red fields. At this point it appears that if the glitch DID NOT occur then switching to the second S-Video option displays a green screen, and if the glitch DID occur then switching displays a red screen: If I go to the "Device" menu, select another device, then select the Hauppauge card, sometimes the glitch occurs. when I'm in "Overlay" or "Preview" mode). I can also get the glitch to occur (randomly) while I'm not capturing (i.e. The first S-Video option displays the actual video stream, while the second seems to display either a completely green or completely red screen. I also noticed that under the "Video sources" menu in VirtualDub there are 2 S-Video inputs and 2 Composite inputs: They were taken from the start of two separate captures and no frames were cut from the beginning. "bad.avi" has the glitch, "good.avi" does not. avi captures (encoded with HuffYUV) to MediaFire here. Here are 4 sequential frames of the glitch occurring (the first is a "good" frame): Now, this doesn't happen all the time and appears to be random. It turns out that shortly after capturing begins a "glitch" would occur that causes the picture to dim and stay dimmed. When using VirtualDub, I noticed that some of my captures were a little bit darker than the others and decided to investigate. I just purchased a Hauppauge WinTV HVR-1250 yesterday and I believe I have found a bug when capturing raw analog video from the S-Video or Composite input.
