Problem with GSA-4040B?

[joetv]

I have had the LG GSA-4040B writer for about a week now. I am trying to copy dig-8 camcorder footage (anolog from composit/Svid L & R audio) to DVD-RW. The video and audio is choppy (but in sync) intermitenly, mostly on moving scenes, but on still also. By choppy I mean on still or slow moving video, it will jump forward 1 or 2 seconds about every 10-20 seconds, on fast moving it will jump forward every 3 or 4 seconds. I am using a ATI all-in-wonder Rage 128 agp card to capture the video with composit and/or s-vid. I am using the supplied Neo software. The video/audio is choppy if I write to hard drive of direct to disc. I have not tried to burn from any other source. What am I doing wrong?
My system is as follows:
PIII 1 Ghz
Gigabyte MB
256 M/ram
ATI all-in-wonder Rage 32MB agp vid card
40 GB HD 7200rpm
DVD-rom
LG GSA-4040B
*HD (master) and DVD-rom (slave) on IDE 1
*LG GSA-4040B (master/alone) IDE 2

FWIW, I bought a firewire port on the way home, after I installed it, I connected my Dig8 camcorder, made a movie file, it also was choppy. there was no change from making movie on HD or DVD-RW with ATI analog input or firewire. I also used both the NeoDVD and Ulead Video Studio with the same result. I do not have any idea what the trouble could be. Any help would be appreciated.

I don't really know much about capture, but I'd guess your I/O subsystem and hard disk can't write the data coming from the capture card fast enough. You either need to slow down the data rate from the capture card or invest in a PC with faster disk I/O.

Have you benchmarked your HD? The program MPower from http://www.mindbeat.com/ will allow you to test read/write speeds. Compare the results with the Neo requirements. Maybe defragmenting your drive could help a little.

It could also just be your capture card dropping frames for some reason.
