  a little ways back there was a thread “vegas lowering quality” about greenish lines in converted/captured media. I stumbled across this at a forum.

  My video has greenish lines in it.
  Occasionally, I see thin horizontal strips in the captured video that looks like they came from the last frame???

  No one has a rock-solid answer for why these problems occur, but it appears to be caused by contention on the PCI bus, which then prevents the sound card and video capture devices from emptying their buffers in time. This problem is reported more frequently on motherboards that have a VIA chipset, or in systems that have a SoundBlaster Live! sound card. In the former case, try upgrading your VIA 4-in-1 drivers first, and if that is not sufficient, check for a motherboard BIOS update that specifically addresses your problem. As for the Live!, the Creative driver is known to cause problems by lowering the latency timer of the PCI bus. (The result is similar that of making the red lights appear every ten seconds at a four-way intersection.) In that case, try installing the Microsoft drivers instead.

  Also, check the websites for the hardware manufacturers to see if they have utilities which may help. For instance, Pinnacle has a PCI adjustment utility for some of their cards.

  If you are using RGB24 for your raw capture format, switch to YUY2 to drop your raw datarate by 33% (see below), which may be enough to lower PCI bus load to workable levels.
