Hi,
I tried making an array with 1 drive also. When I saw the super high rate of around 80MB/s, I knew something was a miss. Try using the Sandra system analysis software. It gives a more accurate reading as well as some helpful suggestions.
I also had an incident where the RAID controller was set to "DOS compatibility mode" in WinME. That is when I switched from the Win9x_NT driver to the Win2000 driver. After that, it has been working wonderfully
For write cache and DMA, yes I have them both turned on. The previous AMI RAID BIOS did not even have a DMA option. Turning write cache on had the hidden effect of enabling DMA.
Long story short, the reason I am not using Matrox MJPEG is that it drops a lot of frames when capturing from s-video source. I talked to various folks and got it to a point where it was tolerable. Unfortunately, playback was getting annoying as well.
After playing around some more, I figured out how to use PIC MJPEG with a WinTV card in a machine (SVideo capture). It really is a flexible card and PIC is a flexible codec. Using the setup, I can get around 8.5MBs captures for 720x480. The files are very impressive. Using TMPGEnc, the resulting MPEGs are outstanding.
I also started using YUY2 && (PIC || Huffyuv) with the Marvel. For me, it works well at half-frame capure. Still, I was not pleased with the captures. No matter what I did (swap fields, etc.), the captures had a very slight flicker.
Don't get me wrong, I like the Marvel a lot. For Matrox's support only, that card is worth it. I am just waiting for the Win2K drivers to become mature. Still, I'll probably use PIC MJPEG over Matrox MJPEG.
You can not beat the Matrox G400 (G450 as well I hope) for its TV-Out capability. I have yet to find a tv-out that looks nearly as good. This is funny, but the only issue I found is that the G400 does not playback PIC MJPEG files in the TV using AVI_IO. Using any other tool, playback happens. This is something that annoys me, because I really like AVI_IO.
I wonder if Markus knows of this?
