De-interlaced recording codec

[Jelleke]

Hi,

First of all i want to say that i know that de-interlacing is bad for videofiles to be played on the tv but it's for videofiles on the pc.
I'm looking for a codec that records and de-interlace at the same time!
A codec with high quality that don't expect a super high computer speed, because mine is not bad but not all the codecs work fine on my computer.
I now record using the PicVideo MJPEG codec, that's a very good one but i can't record de-interlaced. I allready looked for much codecs but can't find one! Who can help me?

Then another little question about de-interlacing. I looked up much information because i first thaught my tv card was bad but when i know now why it comes i still want to know 1 thing about it. Why are the dvds you buy at good quality at pc and tv and not de-interlaced? Or are they?

Thanx,
Jelle
