Sorry if I have offended anyone I was trying to keep my responses short. Also I have not been able to respond quickly this time.
In answer to one question, yes I have a DVD burner in my computer. What I am trying to do is to add a few short maybe 10 second clips to vacation slide shows. I have seen this used very effectively by various people. For instance one person I know used a few small clips from "Titanic" in his slide show for a boat trip vacation. It was cleverly done and was very funny. I would burn the slide show to a DVD for showing to my family and friends only.
I think I did answer all the other questions asked and did follow up on all the suggestions except defrag. The place where I put capture video temporarily, is a 130 GB partition on a 200 GB disk(2nd HD). This partition is normally empty except for a few file folders which amount to a few GBs from pictures. I just checked it and Windows shows there are no fragmented files. I seldom leave anything there very long and it was essentially empty for the capture tests I ran. Could the fact it is a partition be a problem? There are three other partitions on that HD, one each for automatic backup twice a week with Disk Image 7,0 for the three computers in our household. The backup occurs while we sleep so I don't think that is interfering with capture?
I tried capture again with my antivirus turned off. No help.
Someone suggested that Roxio does not handle capture with USB very well. I tried sending the signal to my Hauppage TV Card, but I could not get it thru into my computer.
Again I am sorry for any offense I caused. I do need help in solving this problem.
