Comment 137 for bug 439163

not sure if this is related or not but I'm using Ubuntu 10.04 with the 20100517 fix. The channel scan works fine for me, but for a particular multiplex whenever I try to watch any channel I get the L_S partial lock.
The same channels work fine in Kaffeine; could somebody please suggest any steps to troubleshoot this?
Is there any direct recording I can try on the command line to see if the problem is mythtv-related or something else? It looks like it's only mythtv as Kaffeine displays the channels without a problem.
