Frank,
I have put my answers in between your text, I hope that is clear
enough.
This reply should give answer to questions of others, if not sorry,
could you ask specifically what I need to tell you?
PS: The movie also looks very bad on tv, a lot of stripes and not
fluent video.
Thanx,
P

This is quit surprising, I thought the camera's were digital.
However, I don't know the settings that were used.

I ran DXDIAG.EXE and the DirectX version is DirectX 9.0c
(4.09.0000.0904)

I will remember this one when filming myself. As the two files were
shot with camera's that are not mine, I didn't have any control over
the settings.

In Premiere I found that the Frame Size = 720h 480v
FrameRate = 29.97
Pixel Aspect Ratio: D1/DV Pal (1.067)

In the setting for Premiere I see the Compressor used is indeed Cinepak
codec by Radius.
The other that I see in the list are:
- ffdshow Video Codec
- Indeo Video 5.10
- Intel Indeo Video R3.2
- Intel Indeo Video 4.5
- Intel IYUV Codec
- Microsoft RLE
- Microsoft Video 1
What would have been a better choise????

I use Premiere 6.0, for now, I want to upgrade, but I don't know if the
project file (ppj)
I created in 6.0 will load in Pro 2.0

As I wrote above, it is at a frameRate of 29.97 and Sie is 720x480.

This I don't understand, the input files are of good quality.
If I could improve the output quality of Premiere, I could just export
to Movie again, no?

As I wrote above, I don't have a DV codec (at least, it seems to me I
don't).
So I'm not sure on what to do the check for a better output quality.

I opened the project as a DV - PAL : Standard 48kHz.
I hope you can help me further with this info.
It seems to me however that the output was done with 48kHz en 29
FrameRate, so it should be fine, not?
Thanx a million for looking at this problem I'm having,
