How to convert mpeg2 file from interlaced to deinterlaced?

[key master]

I want to record a snippet from a show on TV, for example, from BTV to include in an MPEG2 file to be played on a computer monitor using plain 'ol Windows Media Player.

I downloaded dscaler but that doesn't convert the file as far as I could tell, it just *plays* it deinterlaced. It doesn't actually deterlace the file which I need something to do.

Does anyone have any ideas? I assume if you enable "hardware deinterlacing" in BTV it behaves the same way as Dscaler - it deinterlaces the interlaced recording only as you play it... or does it actually save the file as a deinterlaced recording in the first place?

Did any of that make sense?

Thanks,
-Jim

you are going to have to re-encode it using something like tmpgenc and set the software to deinterlace it or output in progressive format
