Hi
I'm trying to use vlc to view DVB-T on Ubuntu 7.04 (edgy)

I start vlc with
vlc -vvv --ttl 12 --program=561 dvb: --dvb-adapter=0 --dvb-frequency=226500000 --dvb-bandwidth=7

The error I get is

Code: Select all

libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 1) for PID 0
Full output is

Code: Select all

I got this error always, but it worked anyway.

Do you get a picture?

Hi,

VLC doesn't recieve the right packet (PES). If this error appear only on a few packet then you can watch the video. In your case, you seem to have error at each packets.

If you are using an USB stick, is your USB host compatible with USB2 ?
