I have a Dell Dimension 2400 running XP Home User edition with P4 at 3 gigs with 1 gig of ram and 120 gig hard drive. Got a Sony DCR-HC40 camcorder. Tried 3 different Firewire cards (Adaptec, Belkin, Lucent) and 3 different editing programs (Power Director 3, Pinnacle Studio 8, Ulead Video Studio 5) all with the same result. There is no video shown in the play and record window. Pinnacle program says it's trying to connect to camcorder thru firewire but nothing happens, Power Director accesses camcorder and controls allowing you to fast forward, rewind, stop, etc. the tape but no video or audio shows up. tried many suggestions found in discussion groups but nothing works. Divice Manager shows IEEE 1394 card installed and working properly and camcorder under imaging device. At my witts end. can somebody please help?
