WDM driver under Windows XP looses a field?

[nsdn]

Hiyah,
Well so far I quite like win xp except for trying to find BT878 drivers for my capture card.

I found this web site but what concerns me is this:

Q8: Why VirtualDub software fails to capture a frame higher than 288 (240) pixel rows?
A: VirtualDub, like any other VFW based software, uses so called wrapper to translate VFW calls to their counterparts in "DirectShow/WDM world". This slowdowns your PC a bit, and the wrapper grabs only one TV signal field. This results in only 288 lines for PAL/SECAM and 240 lines for NTSC. I think it would be possible to modify a wrapper to solve this problem but unfortunately I do not have enough free time and special equipment to work on it.

Does this mean that when you use XP or win 2K you are forced to throw a field away???

That really sucks big time....need every line u can get when u are capturing those VHS tapes

Anyone know how to get around this?

I sent a email to Avery Lee, tho I expect he will be too busy to read it

Think I answered my own question, on the link above he also has a capture utility. will give it a go tonight and let people know if it works
