I get exact same problem if I load drivers without NTSC patch, make sure the patched drivers are loaded instead of non-patched. On my system I've built kernel and DVB drivers as modules. After system starts I unload kernel drivers and load patched dvb-kernel drivers from CVS. (dvb-kernel/build-2.6/insmod.sh unload; dvb-kernel/build-2.6/insmod.sh load) Check with "lsmod" to make sure all DVB drivers unloaded after "insmod.sh unload", if something is not unloaded, add it to the script for unloading.

Hi,
I have described my problem with NTSC output for North America in my previous post. I did apply suggested patch but it didn't solve my problem. Now I would like provide more details for the problem.
If I start VDR without tuning to any channel I will get "rolling" picture on TV in B/W (it looks like PAL mode). But if I use szap and tune the DVB-S card to some channel I will get correct picture on the screen of TV. Then if I start VDR and tune same channel I will get correct picture/sound. So, it looks like if the card find signal it will work in NTSC mode (weird behavour).
Other problem I found is that if I switch between channels on the same transpoder I will get picture/sound (TV channel) or sound (Radio channel). If I am on radio channel I have "rolling" screen and B/W picture. It looks like I am in PAL mode again.
But if I switch to other transpoder I get no picture and no sound and "rolling" screen again.
What is most interesting I never had a problem to tune up by using szap program but can not do it in VDR. I guess that it somehow can be related to patches I applied for plugins I use. I will recompile VDR without plugins to see if I am right about it.
Is there somebody uses same setup as mine for North America? I would like to hear about your experience.
I have next configuration
CPU: Athlon 1.2GHz RAM: 512MB OS: Fedora Core 2 VDR: 1.3.22 Plugins: rotor remote control DVB-S: Nexus-S 2.3 Location: North America/Canada
