 Some words about Siemens-DVB card support.         by A'rpi
 ==========================================
 
 Requirements:
 ~~~~~~~~~~~~~
-- Siemens DVB-S card or compatible (technotrend,galaxis,hauppage etc)
-  see www.linuxtv.org for details and download latest driver there.
-- MPlayer-CVS, ffmpeg-libavcodec CVS are recommended for speed & pp.
-- Fast CPU - 1GHz+ recommended at least for software transcoding (divx->mpeg)
+- Siemens DVB-S card or compatible (Technotrend, Galaxis, Hauppauge, etc)
+  See www.linuxtv.org for details and download latest driver there.
+- MPlayer-CVS, FFmpeg libavcodec CVS are recommended for speed & postprocessing.
+- Fast CPU - at least 1GHz recommended for software transcoding (DivX -> MPEG).
 
 
 How to enable?
 ~~~~~~~~~~~~~~
 
-    ./configure should detect it. If didn't, force with ./configure --enable-dvb
-        If you have ost headers at non-standard path, set it with:
-	--with-extraincdir=<your DVB source dir>/ost/include
+'./configure' should detect it. If it did not, force detection with
+
+    ./configure --enable-dvb
+
+If you have ost headers at a non-standard path, set the path with
+
+   ./configure --with-extraincdir=<your DVB source dir>/ost/include
+
+Then compile and install as usual:
+
     make
     make install

-  Note: the DVB card only supports height 288 and 576 for PAL,
-  240 and 480 for NTSC. For other heights, you MUST rescale it,
-  by adding 'scale=w:h' to the -vop option, where w:h are width:height
-  you want. Note, that DVB card accepts various widths, like 720, 704, 640,
-  512, 480, 352 etc, so you don't need to scale horizontally in most cases!
-  (the card will do hardware scaling in horizontal direction!)
-  For example, for a 512x384 (aspect 4:3) divx try:

-  Do you want osd, and subtitles? Use the expand plugin's osd feature!
-  So, instead of expand=w:h or expand=w:h:x:y, use expand=w:h:x:y:1
-  (the 5th parameter :1 at the end will enable osd rendering)
-  You may want to move image up a bit to get bigger black zone for subtitles.
-  And you may want to move subtitles up, if they're out of your TV screen,
-  use the -subpos <0-100> switch (-subpos 80 is perfect for me).
-
-To play non-25fps movies on PAL TV, or with slow CPU, add option:  -framedrop

-To get the optimal scaling parameters (use hardware for X scaling, and
-scale Y by software, keeping the right aspect ratio), use the new 'dvbscale'

 Future plans/TODO:
 ~~~~~~~~~~~~~~~~~~
 
-- display OSD and subtitles using DVB card's OSD feature
+- display OSD and subtitles using the OSD feature of DVB cards
 - better (more fluent) playback of non-25fps movies
 - realtime transcoding between mpeg2 <-> mpeg4 (partial decompression)
