A very interesting video but I wonder if any of the Mayhemmers can explain why, when I am watching virtually any video the picture keeps stopping and I get circulating small bars in the centre of the picture and then the video starts again only to continue going through this annoying process time after time. >:-o >:-o  It takes ages to watch any lengthy video and I wondered if it was anything to do with the video card in my PC. {:-{ {:-{
Thanks guys. :-))

Derek,

I get the same. I am told it is the result of a slow download speed such that your replay speed is running faster than you can download the item.

I find sometimes that if you pause the replay your download will overtake your replay and then you can watch the whole thing without breaks. But it does not always work for me. If you look at the horizontal bar below the replay screen you can see the replay point (a disc with a dot in it) and creeping along behind it is a shaded line showing the download being achieved. After and following the dot is the replay being achieved (shown by a solid line). Clearly if the dot overtakes the shaded line your picture will freeze unti the download catches up!

Thanks Roger.  I will give your suggestion a try, but was also wondering if I needed to upgrade my video card (although I wouldn't think so as it is a fairly recent PC and running Vista Home Premium).

Your video card should be fine,its as Roger said,your pc is playing faster than the download.
Saw some of these machine working at a F1 factory last year.
That helmet,probably took 2/3 days to make,amazingly accurate.

Thanks, Mark.  No wonder our cars, etc., are machined to such fine tolerances these days. :-))

As Roger says it is all to do with download speed and not the video card.  It is basically not downloading fast enough so the video catches up with amount of the file that has been stored.  This is called bufferring and the best solution is to pause the video until the buffer is big enough for the video to reach the end without catching up with the downloaded file.

I pause the video, and wait for it to load, then play it through.

I thought CNC machining a barge out of koa wood was fun,... That machine
certainly out does anything I have access to...  :o

In the first video the small circle on the enclosure is a view port with a wiper. when those machines are normally running you can't see the part for the flood coolant. Because they were cutting dry for the video they probably had to slow the cutting rate down.

Or they cut it wet, and perhaps for the video they were only going through the motions on a pre cut piece for most of the video. I only really saw milling on a couple of occastions.
