thanks, I had seen your thread from a while back. I'll take a closer look at it this weekend...it sounds like the updates were applied to the contrib directory so they should already be in there. but you never know.<br>

I had this problem back in the day and now it works if you use firewire to view the content. Here is something from the thread. If this doesn't help let me know and I'll try to pull out my notes. It is a patch that you can apply with the diff command.

The behavior you are seeing is similar to what I saw when I allowed mythbackend<br>to use its internal <span name="st">channel</span> changing code for my SA3250HD. I too would get<br>changes to <span name="st">
channel</span> 48 for a lot of different channels I tested on.<br><br>I am attaching the diff for my changes to mythtv/contrib/sa3250ch.c.<br><br>You'd have to grab sa3250cs.c from svn, patch it, compile it, and install it
<br>somewhere, then in the mythtv-setup screen (I believe it's when you link the<br>video source to the capture card) where you can define an external <span name="st">change</span><br><span name="st">
channel</span> command, you put the full path to sa3250ch that you built and installed.<br><br>I got this patch from someone in the #mythtv-users <span name="st">channel</span>. Their SA3250HD had<br>a different vendor id as displayed when using gscanbus, so they updated the
<br>sa3250ch.c to recognize the particular vendor id of their hardware. Mine<br>matched the vendor id already in sa3250ch.c, so I left it alone and just made<br>the changes to the code that sends the commands.<br></div>
