I went out and purchased one of the Belkin USB video capture devices and at best, the performance is very poor... I think they say 30 fps but I'm not seeing it... No where close.. I may need to do a bit more tweaking but this is actually what I expected after using the internal PCI cards to capture security cameras on a number of projects.. They just don't seem to work as advertised... At least not for me.

I'd like to know what other options we have for in the field capture... I want to be able to offer the customer a copy of the video downlink if they would like on a DVD..

Here is what I can see at this point..

Mini DV with Video inputs to record from an outside source
Mini 8mm video recorder
Full/Medium sized vcr (wouldn't that be fun to tote around)
Direct to the laptop via input card or device (isn't working well)

Am I missing anything?

Try a firewire capture box instead of the USB. Here's one I have had great success with on a mac.

Part of the issue is whether the capture device depends on your computer processor to do the work or has its' own.

If the capture device is just a dongle looking thing that plugs into the USB port, then you better have a beefy system, with all other processes shutdown.

The units with their own processor generally are a largish box with a power adapter. I have a WinTV PVR-usb2 unit, it is about 5"x5" in size.

Check the specs: does it have a hardware MPEG2 encoder ?

Thanks for the info. With regards to the USB dongle, my processor levels looked about 40% and plenty of RAM.. I also made sure it was mostly going directly to the HD rather than being processed..

Now, for the good news... I went out and purchased the Pinnacle System's PCTV Deluxe (they were out of the one mentioned above) and am watching TV in a small window as I type this. It also has S-Video, composite video, and L/R audio inputs. I plugged up my sony camcorder and played a pre-recorded video, then a live link to the Pinnacle system and it recorded perfectly.. Both MPEG-1 & MPEG-2 are covered and offers all sorts of options.

Not sure if I got a good deal @ $199.99 at Fry's, but I didn't want to wait.

It isn't exactly ultra-portable as it has a wall-wart and is the size of a small cable/dsl modem, but will work out good in the mobile office..

Thanks again for the input.
