</div></div>So MythTV used to work with your TV with the old cable and doesn't with the new cable? Is it possible that the old cable wasn't setting up a good connection to the Myth box and the video display was taking a guess. Now you can get a good EDID through the new cable and your Myth box doesn't have the right drivers? If so, then it is just a matter of debugging why your Myth box doesn't like your TV now that it knows what it is.<br>
<br>
The alternative is that the cable isn't working with your setup which seems easy enough to check by returning one of the two cables you got and trying the other kind that was offered.<br>

</blockquote></div><br>god knows what the issue is; these new cables dont seem to like the mythtv pc. work fine with everything else, and other cables work fine with mythtv.<br>i think i'll swap cables around to get a working setup for tonight, and see what they can do for replacement tomorrow..<br>
i think i might look at upgrading to 11.04/0.24.1 next week and see if i suffer the same issues.<br><br>thanks for the sugestions..<br>
