Hi group,
I'm having a problem with capturing video onto a PC.
I've built a system for the sole purpose of capturing video from my Sky+ box. (Composite video input.) Thing is, it drops frames at a stupid rate, rendering any captured video useless.
The system was originally an Athlon-850, and I could usually capture on that with no problems at all - one or two dropped frames here and there, but nothing that would cause any major problems or loss of sync. Since I stuck in the 1900 and did a clean install, it's been hopeless.
I went for the g450 card as I'd not had any luck with seperate capture cards and wanted to try a different approach.
I'm currently using Matrox's own PC-TV software just to get the thing up and running before I invest in an capture/editing package. As soon as I hit the Record button in the software, it tells me it's already dropped 5 frames! By the time 30 seconds have gone by, it's dropped another 27 or so frames, knocking the audio-video sync out.
Matrox's software gives me the option of capturing in MPEG2 mode, or YUV mode, neither of which work particularly well.
Surely an XP1900 is fast enough for capturing video without losing frames? I'm running the latest nVidia chipset drivers, latest Matrox drivers.
The 20Gb drive has been defragged and the 60Gb has been clean formatted, which made no difference at all.
Any ideas?
