This is second hand information because my HDV camera is still in the shop.
I'm waiting for 1080p :)
Anyway. there is program called mpegrab or similar which can grab trough
firewire the uncompressed video. The need of

Are you considering hard disk recording of uncompressed HD video?
That will require a striping RAID, so it will be heavy and pricey.
You might as well get a semi-pro camera with SDI-HD output, which
is intended for such use.
Or

Note that Cinelerra does two tasks: render and display.
To render, Cinelerra treats the 1440:1080 as square pixels. This is not
optimal if something you render has both horizontal and vertical extent,

When camera is operating, the EIP generates uncompressed 1440x1080i with
a 4:2:2 color space. Digital 4:2:2 data are output via the HDMI port,
while 4:2:2 analog is output via component out. Therefore you can record
4.2:2 live HD cideo from the camera without MPEG-2 compression.

Terje,
That's interesting information. Steve Mullen knows his stuff.
One thing to remember is that if you don't want to spend the money on an
external hard drive recorder, you can use a laptop with firewire to
capture the incoming stream using VLC.

The display has to be stretched by the player. If Cinelerra is told
that the resolution is 1440x1080 and the aspect ratio is 16:9, it
HDV 1080i uses a pixel resolution 1440x1080 on tape. The rectangular
pixel aspect ratio h:v=4:3=1.33, so when displayed the video frame is
scaled to an aspect ratio of (1440x1.33)x1080=1920x1080 or 16:9.
What I wonder is:
