reboot as requested, but still no display once mythbuntu
starts to load.<br>

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>

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>

I had a similar problem: no problem with a DVI to HDMI adapter and a
short cable. But when I changed the short cable with a longer one
there was no picture.<br>
When I connected my Nvidia card with the adapter and the short cable
to the audio amplifier (Yamaha) and from there to the TV (Sony) I
had no problem.<br>
<br>
I suppose the signal from the PC was just too weak.<br>
<br>

my only sugestion is their was some residue on one of hdmi connectors that has now rubbed off with the various testing of what works and what doesn't.<br><br><br>ahh, the joys of tech!<br>
