I have my Barco 701s connecetde via VGA >> 4 x BNC from a Quadscan pro and also via a standard 10m S-Video cable. My DVD player is a Toshiba SD900E M/R which feeds component interlaced to the QS and also S-Vid to the amp which is in turn also delivereing an S-Vid feed to the QS for Sky etc. For some strange reason over the past few weeks I have noticed regular brightness fluctations whilst watching DVDs via the direct S-Video feed (Source 2 on the pj). I certainly do not remember noticing this for the first few weeks and certainly do not get it via the QS feed (even if I switch that to the S-Vid input). I read somehwere that this may be caused by macrovision but cannot understand why it has suddenly appeared. Anyone got any other suggestions why this may be happening. Could it be a faulty cable or interference from an outside source? Thanks.
