Capturing with Scenalyzer has pixels

I've been trying to capture with Scenalyzer but when I hit cature or batch capture it has pixels in the clips. When it plays without capturing I get no pixels. I have tried cleaning the video heads also switching cameras but nothing works. The only way I can have success is to Analog capture. With the old version of sclive I never had the problem. I currently have Sclive Version 4.0 . I love the software but am puzzled as to what the problem is. Any help would be appreciated.

Thanks in advance
Harry

After remembering how I corrected the problem months before. I found I had to capture to my "C" drive in order to get the best results. No Pixels. I went to the SClive manual and found this,


"Hard disk speed test
Informations about hard disk speed and buffer size:
DV capturing writes data with a speed between 3.5 and 4 megabyte per second to the
hard disk, which is unproblematic for modern hard disks.
However, if the hard disk is busy during capturing for several seconds with other
functions and cannot store the video stream, ScLive stores the data in a RAM buffer
and writes it to the hard disk later. ScLive dynamically uses a maximum of 50% of the
main RAM as buffer. In the bottom status bar of the main window, you find a bar
displaying how much of the buffer is currently used.
In the rare case that the error message “Sorry, your hard drive was not able to write
fast enough“ is displayed during capturing, please use the function File > Tools >
hard disk speed test to check the speed of the partition or disk where the capture
folder is currently located. With this function, ScLive writes a video file on the hard
disk and shows you the relation between writing speed and real-time. If the result is
e.g., ”ScLive wrote [...] 5.6 times real-time“, it means, that the hard disk is 5.6 times
faster than the required minimum speed for DV capturing.
If however the hard disk is rather slow (e.g., 1.5 times realtime-speed or slower) the
most common cause is that the DMA or UDMA mode for this hard disk or this IDE
channel is not activated in the Windows Device Manager."

I haven't checked yet but I think my problem was in my DMA or UDMA mode. I have three SATA 260gig Drives. The "C" drive is the only one that will get the best results. If I find the answer I'll repost with it.

From now on I'll be capturing to my "C" drive.
