Interlacing/Deinterlacing Issues

I'm using the Canopus ADVC 110 analog to digital converter to import my
Hi8 analog video from my Sony camcorder onto my PC using the s-video
connector into the converter box and firewire from conveter box to PC. I
have used several applications for importing video (Windows Movie Maker,
Vegas Movie Studio 4.0, Nero 6.6). I have imported under several templates
(DV-1, .AVI, .WMV, MPEG2). I realize the preview on all apps are lower
quality than what my final output will be (DVD for TV playback), but is there
anyway to totally eliminate what I have narrowed down to be an
Interlacing/DeInterlacing video issue? All previews on all apps show an
exaggerated interlacing problem. When I burn to DVD, the problem is almost
non-existent, except for when the camera moves (pans or tilts), then you can
sometimes see in parts of the picture the horizontal lines which seem to be
an interlacing issue. If I start with a DV-1 file, then the resultant MPEG2
DVD burn seems to be at its best. If I use anything less than a DV-1 file
for MPEG2 DVD burn, than the interlacing issue seems to be more exaggerated.
Any suggestions to completely elimnate this so my DVDs will be as crisp as
possible? What about the deinterlace filter of VDubMod? Will this help?

Thanks,
Chris S.

What are you watching the dvd on. If it's a std tv then it needs to be
interlaced as that's what they are set up to show, if it's on a pc then
de-interlacing will help.

Would the firewire "card" be an issue? My firewire connection(s) are on my
audio card which is a Sound Blaster Audigy 2, DR release 1.4.2. Would a
dedicated firewire only card improve my video? Are there any known issues
with my current card?

Thanks,

Would it be an issue with what? Interlacing? No. Analogue video signals are
quite poor, you cannot hope to get increased quality when converting it to
mpeg. There were some issues with audigy firewire devices, but having the
latest drivers sorted that, and it stopped them working with dv capture
anyway, so it's unlikely to be this.
For better quality mpegs invest in a good quality encoder, which will do at
least two passes, you could try tmpgenc, which is good, main concept do a
good one, but be careful as they do professional ones which will cost an arm
and a leg, and the best sort of consumer one is Procoder from canopus,
around 300, very good, I use it.
