I expect its a USB speed problem. Maybe the user is only getting
USB1.1


The problem with USB2 is that the speeds quoted are the theoretical
(maximum) speed, AIUI at no time will anyone achieve those speeds in
the real world and as it that theoretical maximum speed that is
needed for real-time video capture....

You either need a PCI (or better) analogue capture board or an
analogue to DV converter (be that a purpose build unit like those by
Canopus or using the 'pass-through' ability of some DV cameras) and
then import via the IEE1394 port.

I am using Pinnacle Studio 9 with their av/dv capture pci card on a amd
2200+.
This combination works very well for me, so I can tell you the problems
are likely in these areas:
1. I do not like usb capture devices. Some computers with some devices do
not properly support usb2, and the earlier versions are just too slow for
real time capture. Hence the dropped frames, jerky video, audio out of
sync., etc.Make sure you can achieve a high enough transfer rate.
2. I do not know the device in question, so I can't say how to change
your capture parameters. My experience is that vhs/8mm capture needs only
352x480 or 352x240 resolution at lower bit rates. Too high a bit
rate/resolution combination puts too much stress on the computer or
device
3. A lot depends on where the compression is done. Some devices do it in
hardware, but Pinnacle traditionally does it in software, which is less
desireable, and less expensive, but CAN give very good results.
Compression is hardware means less data to transfer through to the
software, which means better results for slower computers

check www.videohelp.com and www.digitalfaq.com

I am still learning this stuff, but I will be pleased to offer any
suggestions.

I took the original Studio9 package and the Dazzle package back to PC
World and swopped them for the Studio AV/DV package with PCI card included
(got some change too!)

Everything worked perfectly first time!

Moral: don't even think about trying to use USB2 for analog video capture.

Thank you all for your helpful responses.
Glad you're sorted out now.

I am using Pinnacle Studio 9.4.3 and have had very good results with
digital capture using DV format from a DV camcorder.

So good were the results that I decided to update some of my old home
movies taken with a Video8 analog camcorder. I therefore bought Dazzle
Digital Video Creator 90.

This is a terrible device. Dazzle went out of business and was bought
by Pinnacle. All Dazzle hardware and software are old as are the
drivers, hence many incompatability problems arise.

You might try the Pinnacle MovieBox.

I prever the Hauppauge 250 or the ADS Instant DVD USB 2. I find no
dropped frames, and capture at 8 megabits/sec perfectly with this
device on a Pentium 4 2.6 gig. (I have nine other USB devices
attached).


Forget movie boxes. Better pci card. Like the previous poster, I have
Pinncacle AV/DV delux with breakout box. Works well.

He already captures to .avi....he wants hardware to .mpg

Standard cheap capture devices don't do it,.

My DC 10 has no problem

The DC10 captures to MJPEG , not MPEG

Hauppauge PVR-250 or PVR-350 (Has FM radio) Worked flawlessly on my
old P II 400 mHz/80 gb HD system - the only way I could do any of this
work on that machine! (Speed & Drive space).These are PCI cards.

Just make sure it actually states somewhere that the encoder is
hardware based! I've read a lot of adverts. where they are very
ambiguous about this.
