My ex-wife is having a problem with dropped frames when capturing videos from a Panasonic PV-GS58 DVR. She is using the system listed in my sig and using Sony Vegas Platinum 8 via Firewire connected to the Zonet card.
What I have tried so far is:
1: emptied the temp folder
2: completely defragged both hard drives
3: moved Vega's temp folder to the second hard drive which is reserved for capturing (it has 65gig free out of 80 and the system drive has 20gig free)
4: turned off all programs non essential to video capturing and editing (except for AVG 8.0 which will be the next thing we try)
5: didn't use the system for anything else while the capture was in progress
The camera is not her personal camera. It belongs to the elementary school that she works for and she is using it primarily for school related projects. She doesn't do the maintenance on it and has no idea how long it has been since the heads were cleaned on it.
The tapes she is working on now were good quality ones (not sure of the brand, but they weren't the cheapies) purchased new just before she recorded to them last fall at the beginning of the school year and have only been recorded to the one time.
She gets a rather consistant dropped frame every two minutes or so which leads me to believe that it might be the anti virus program probing the drive (which I didn't think to turn off of that drive at the time). But, if she captures with Windows Movie Maker or NeroVision Express she doesn't drop any frames, but she can only capture using USB 2.0 in either of these (going through the onboard USB 2.0 connector). If she tries to capture with Vegas 8 via USB she doesn't drop any frames, but she doesn't get any sound. This leads me to suspect the Zonet FW card. Between these two things I'm leaning towards one of two things. Either AVG 8 is interfering or the Zonet FW card isn't performing up to snuff (it has a Via chipset, but I don't know specifically which one).
Aside from the obvious of trying it with AVG disabled does anyone else think it could possibly be the FW card? Any other ideas of what to try or check besides getting a head cleaner for the camera?
Thanks for any assistance you experts can provide as this is outside my area of expertise.
