Hi, complete newbie here.
Reading the forum posts here have convinced me to at least make an attempt to capture my 40-odd video8 XR tapes losslessly (huffyuv) instead of going the easy route and using the firewire (lossy DV) method.
Unfortunately, while making some initial test analog captures with my VC500 into virtualdub I'm getting a vertically squished image/frame compared to the firewire DV capture which looks perfectly proportional.
Notice that both captures have a "Display Resolution" of 720x480, but the correctly proportioned DV "Resolution" is a weird (nonstandard?) 736x480.
Both captures below are from the same Sony CCD-TRV730 Digital8 camera - First one using digital Firewire DV output and the second one using analog S-video > VC500:
I can't seem to find a way to force captures of 736x480 in virtualdub, but I'm not sure I should even try since it seems like such an odd resolution.
Any ideas why this is happening or what might remedy it?
Grasping at straws, I suspected that it might have something to do with the tapes being recorded in video8 "XR", so have since bought another video8 "XR" camera with S-video (the original camera had only composite) but it also results in a squished image/short frame.
There doesn't seem to be very much written about video8 XR tapes since the format was only around for a few years.
Maybe I should just drop back and punt and capture them all via lossy DV?
I hate to do that knowing that I would be losing so much color information because of the way the DV codec works with NTSC, especially since there is a slight added advantage of analog capturing XR tapes with an actual XR camera.
I'm kind of overwhelmed yet still hopeful that I can put together a decent analog capture system and workflow.

I wouldn't put too much faith in what Windows tells you. Even MediaInfo makes bad guesses about the metadata sometimes. DV resolution uses rectangular (10:11) pixels to achieve nearly a 4:3 image — which is standard for legacy video. VLC is not finding this ratio in the AVI file so it thinks the image is 720×480 square pixels, yielding a stretched image. All of your data is there. You can just right-click on the picture and choose Video/Aspect Ratio/4:3 to make it look right.
If I'm not heading to DVD or some other format that expects DV resolution, I capture 640×480 square pixels, which keeps everything in happy computer graphics land.
Thanks again for the help!
...now I just need to work on the crushed blacks and audio track that starts way too slow and gradually works it's way up to proper speed.
