Greetings,
Yesterday I added another couple of DV tapes to my computer via firewire for editing. I usually use WinDV for this but I thought I would try MS2024 for the job. It worked without a hitch.
Then out of curiosity I thought I'd try Virtualdub as I hadn't used it for capturing before; just to see if it works. I found it tempremental in that it copied the video with no problem but for some reason the audio was intermittant (I need to play with this a bit more).
I then did a short WinDV capture and compared all three in MediaInfo.
NOTE: all miniDV tapes were recorded using the same Sony TVR18E camcorder

I appreciate the virtualdub clip is very short but that shouldn't alter the interlacing should it?
And why do both Magix and WinDV show "Top field only" instead of Top field first?
To completely throw me, I capture my sons wedding using WinDV and this gave the interlacing as Bottom filed first (same camcorder):

I've not noticed these discrepancies before and I've not had any trouble with editing but should I be concerned?

ps apologies for the length of this post and for adding probably too much Mediainfo info(?).
