Hi, sorry, my mail was down and I couldn't answer sooner.
You're right, I forgot to include the howto in the patch.
Here it is:

Hi,
this patch for mplayer-cvs adds three things to the existing code (that is actually broken)
1) OSD menu of channels 2) howto instructions in DOCS/en/dvbin-howto.txt 3) recording to a recompressed format is now reliable (doesn't break at the first EOVERFLOW), but continues with eventual glitches in the recorded stream; as usual the more powerful CPU you have the better.
As always non-FTA channels are not supported and mpalyer hangs when you select one of them, so please remove them from you ~/.mplayer/channels.conf.
As the tuning code is taken from dvbstream, my patch always uses INVERSION_OFF, so it might suffer from the same problems reported some days ago by some DVB-T users. I'll update the code as soon as I have some more information about this issue.
Feedback and suggestions are welcome.
Thanks, Nico
Thanks for this patch, but i cant find the howto and when trying to just read the input of the tuned device or when opening the input with mplayer i get no output. Could you repost the howto, or give me an information on how to solve that?
