[linux-dvb] Re: Haupauge DEC 2000 stops tuning

[Jan-Simon Möller <dl9pf@gmx.de>]

I tried dvbstream ... nice - multicast over network ... with this tuning gets 
easier. Just kill dvbstream and let mplayer/xine run on dumprtp.

But the same problem with tuning after 4-5 zaps.

normal operation:

dl9pf@frodo:~> dvbstream -f 554000 -v 513 -a 651 -ps 651 513

look at the size and the bitrate / freq ! my be an error in recognition, init 
or sync ??

BTW I'm using ohci (ehci). The Dec is on an pci usb 2.0 card.
Same problem on MoBo usb.

Bye!
