Both myself and a colleauge recently found that passing a signal to the Z1 via the VGA port resulted in it dropping frames. We noticed this when we upgraded our BriteView video processor to the new firmware which seems to have made the problem more apparant. The IScan Ultra was also tested and this was even worse! This is a problem with the Z1 VGA port, not the video processor. It seems the VGA input is pants at handling pans. This problem is most noticable on wide pans, where the picture appears to stutter. I've foud the picture unwatchable because of this. has anyone else had this problem?
