I'm compleately new to this so, please, bare with me.
I've tried searching and the file I get from the links in the sticky is corrupt.
What is the best video codec for progdvb, where can I get it and how do I install it?
My picture currently looks like piture from an analog TV. Why is that? (using the elecard decoder)

You can try change codec or video render in Settings->Options->Video.
For example install PowerDVD and select this codec in ProgDVB.

Thanks for the response!
So all I have to do is install the codec and it'll show up in progdvb menu?
Which codec is the best?

I have divx installed. How i can change codec ?
Settings, options, record there is only mpeg2, TS and mpa
TS works best for me but 1 hour record makes file size 1,7 gigabytes.
Using 6.02.02 standard edition

The DivX codecs are not made for MPEG2, the most common compression for DVB. They simply can't open it.
You need an MPEG2 codec, like from a DVD player software, as mentioned before.
The file size of a recording represents the size of the streams, exactly the way they were transmitted. Else the signals would have to be transcoded on-the-fly.

Tested to record 6 min and 14 seconds television program
Finnish channel SUBtv / Hauppauge HVR1100 card
Elecard mpeg2 video decoder: file 162 Mb
Cyberlink Video/SP BD-HD Decoder (PDVD8): file 165 Mb
Cyberlink Video/SP Decoder (PDVD8): file 174 Mb
ffdshow Video Decoder: file 154 Mb
Nero Video Decoder: file 175 Mb
Tested 2 another channels, same time, ffdshow decoder and
file size is 154 Mb and 21 Mb (this was only music and
few pictures sliding)
So there is no more ways to shrink file, it is just
the size of stream ?

Settings, Options, Record, TV channel recording format: mpeg2
This would be my next question, what difference is in TS and mpeg2 ?
Same channel, same 6min. recording time, TS (.ts file) makes 211 Mb file and mpeg2 (.mpg file) 174 Mb
And i use VLC to watch, .TS opens ok, no problem and .MPG file contains only black screen, only voice.
Tested Windows Media Player (XP PRO, sp3, player version 9) opens .MPG file ok but i do not want to use MS sh*t...

mpg more popular format, but TS more stable.
PS: Size of file depended only from channel.

Why VLC does show only black screen (voice is working) ?
I have used it years now and it opens almost everything but this .MPG file it does not show.. Strange..
I tried Elecard and ffdshow to decode, same thing with both of them
I use VLC version 0.86i and other .MPG files work.
I have only ffdshow codecs installed now.

VLC normally uses it's own set of codecs, not those from the system.
May also occasionally bring it's own limitations.
Anyway, TS format may lead to slightly bigger files, as some extra data may be included, like perhaps crypt system related, or even multiple audio streams. Also possible, an extra constraining may result in a slightly bigger file.
And please keep in mind, DVB transmissions have variable data rates, so even two recordings of exactly the same length and station may differ in size.
However, the file size can only be reduced by post processing, transcoding of any kind.
