Capture Problems with SATA

[lemming911]

Hi All

Recently upgraded my PC to a XP2700 in an Albatron KX18D Mainboard with a Samsung 120 GB SATA HDD. All works well except when I try capturing video from a PCI Brooktree BT878 based capture card. I get corruptions in the video only when I capture above a certain resolution. As an experiment I installed my old IDE HDD and it doesn't suffer the same problem. I noticed the SATA controller is listed as connected to the same PCI-PCI bridge as the physical PCI bus. I assume (not knowing exactly what this is)that there may be a bottle neck through this device. The easy fix I guess is to credit back the SATA drive and purchase a IDE HDD but thought someone might know if this is in fact what is happening and if a fix is possible.

Cheers

The first motherboards with SATA chips used the pci bus for bandwidth so there will be saturation if you're using devices like usb, ethernet at the same time, with resulting capture problems. Newer motherboards have the sata controller as part of the southbridge which allows the full 150mb/s bandwidth. It's probably better to go back to IDE now and get a sata drive when you get a newer motherboard.
