[vdr] Mplayer-plugin output blocky..

[Ari Huttunen <ari.huttunen@f-secure.com>]

I finally got this plugin installed (*), but I find the output is not 
quite ok. There's too much
blockiness in the picture on the TV. My test case is (almost by 
accident) the closing
credits of David Attenborough's Life of Mammals. The original quality is 
pretty excellent.
In case you haven't seen it, there's a video playing on the background 
and credits rolling
at the same time.

What I mean by 'blockiness' is that when there's a lot of movement on 
the screen
and there is an area of a particular color, I can seen that the area has 
very easily
seen 'blocks'.

I encoded this the video with ffmpeg using 1500, 1800 and 2500 kbit/s video
rate, MPEG-4, hq mode, two passes. I took the mplayer.sh from net.

Results:
(Only blockiness mentioned, of course the smaller kbit/s had other 
effects as well.)
- Viewing any quality .AVI file with the mplayer-plugin had almost the same
 amount of blockiness on the TV. I also tried playing with deblocking 
and automatic
 postprocessing filters in mplayer command line: same effect.
- For comparison I viewed the files with Xine on a computer monitor.
 When I played any file with full postprocessing, there was no blockines.
 When I played the 1500/1800 kbit/s versions, with no postprocessing, 
they had
  blockiness in them, 2500 had almost no blockiness.

Comments, suggestions? My hypothesis is that the MPEG-1 transfer rate of 
my TT DVB-C 2.1
is not sufficient for playback You see, I tried setting the 5000kbit/s 
rate to 10000kbit/s, and
the video started playing, hmm.. unevenly at those closing credits. 
Maybe the video
should be converted to MPEG-2 for playback?

(*) There's more trapholes in the installation of this plugin than in
Swiss cheese.. and I fell in quite many of them. And the installation 
instructions
are lousy. But still, it's in. :)
