Problem: libdvbpsi error (PSI decoder): TS discontinuity

[bubbleguuum]

I have "libdvbpsi error (PSI decoder): TS discontinuity" messages every 6 or so seconds. For some reason TS packets are dropped, which garble audio/video repeatedly.
The card is a WinTV Nova-T (DVB-T) under kubuntu's kernel 2.6.12. VLC is the svn version from a few days ago. dvbstream works perfectly without dropping TS packets: /usr/bin/dvbstream -udp -net 192.168.250.229:3000 0 110 120 130

Any help concerning this problem would be greatly appreciated ! At this point I don't know if it is a libdbpsi bug or a linux-dvb bug or a driver bug....

I'm also having a similar behavior. I've posted the info in another post related to the same error:

What's problem with libdvbpsi??

The card is a WinTV Nova-T (DVB-T) under kubuntu's kernel 2.6.12.

2.6.12 is a very very very old kernel for the dvb drivers. You should at least update these drivers, i.e. install the latest dvb drivers from:
http://linuxtv.org/
over the kernel 2.6.12 or event better compile a new kernel. The latest kernel version is 2.6.21.1 but for stability (or easier configuration when starting from 2.6.12) it may be better to use 2.6.19.x which is already much better than 2.6.12.
