Subject: [MPlayer-dvb] DVB streaming read failed after running tzap
Message-ID: <CAN6EUtuv3vHdwK=ci6M9CmyecvQD4gmbVvecF9yziVTnqSdwjQ@mail.gmail.com>

I'm new to this mailing list, so excuse me if I'm posting to the wrong place.
I'm using a DiBcom USB module on an Ubuntu 11.04 host. The v4l-dvb
drivers were downloaded via git and built on June 13, 2012.
Basically, I can watch DVB-T by running mplayer (version
SVN-r35003-4.5.2); however, if I launched mplayer after running tzap,
I would get a series of "dvb_streaming_read, attempt N. n failed with
errno 0 when reading 2048 bytes" failure messages. I must unplug the
DiBcom USB tuner and plug it in again so that I could relaunch mplayer
to tune to a DVB-T channel.

The console output of running mplayer as well as tzap is as attached below.

Has anyone experienced the same problem?

why on earth are you running mplayer dvb://  alongside tzap? there's no 
reason.
tzap is needed to tune the channel and stream its content to the 
appropriare dvr0 device,
mplayer when run with the dvb:// syntax does the same thing so
1) either run only mplayer dvb://
2) or run

tzap -r -c .tzap/channels.conf CTS

and on a different terminal run mplayer<  /dev/dvb/adapter0/dvr0

Subject: [MPlayer-dvb] corrected interaced DVB-video from vdapu card to TV
	SET
Message-ID: <20120630115147.297ae1f7@bk.ru>

Hi

is there any sense to try to output interlace dvb-video 576i or 1080i from vdpau nvidia card to TV set ? 

I heard that there is some issues (timing ?? ) ? that's why it will be very difficult to send
on TV correct interlace signal.   Correct ? 

Am I right that the best solution is to make deinterlacing (temporal spatial)  and upscale (576 -->
1080) with card, not with TV ?
