[mythtv-users] S-Video Challenges

[Rob Ogle]

It's a Mythbuntu 7.10 distro. PVR 500, 2.2GB RAM P4 3GHz cpu, 160 SATA. 

 

I'm seeing a blue line with an otherwise blank screen. I'll try to find the
xorg.conf file and tinker with it. Thank you.

 

I decided to "punt" because I promised someone that I'd record some shows
for him tonight. I hooked up my standard monitor to the vga so I could now
see the menus, only to realize that all channels above 13 show static! Of
course, the channel I need to record is 16. I have the cable coming directly
into the tuner/coax on the pvr 500. 

 

I keep hitting issue after issue. I'm beginning to wonder if the $10/month
to Comcast will be easier than all of these headaches.

I'm not clear on just what your problem is.  Are you seeing the normal
frontend screen and menus, but you also see a blue line across the top, or
are you just seeing the blue line and an otherwise blank screen?  

I think I had a similar problem on my Mythbuntu system, where I saw the
normal frontend screen/menu, with a blue line across the top. I corrected
the problem by setting the option "TVOverScan = .80" in my xorg.conf , and
by tuning the "gui size" in the frontend setup (I'm not in front of my
machine right now, so I'm sorry if the syntax or terminology isn't 100%
perfect; it should be good enough for googling specifics). 

If you're unfamiliar over-scan, my off the cuff definition is that it causes
the display size of your signal to be larger than the screen size, and it
puts the edges of the image outside of the physical edge of the screen.
This is how most SDTVs normally work, and is why normal TV always seems to
fill the entire screen.  It's a bit of a challenge to live with on a
computer monitor, and therefore takes some special settings on your
nvidia/tv-out setup, but with the right tweaking in Mythfrontend, it can be
used to make things look right.  

I hope this helps.  If what I describe is not your problem, ignore this post
and try to describe what you're seeing better.

I'm trying to get my myth box to go through my tv. I have an s-video to rca
converter going from my nVidia GeForce card to the tv.

When I boot the box, I see the myth logo and moving status bar. When it gets
to part where it normally loads the FE, I get a small blue line (same color
as the default scheme) across the top of the tv. 

 

My guess is that this is a common problem. I just can't find it on any FAQ
or manual pages. 

 

Suggestions?

It sounds like you are using a pre-built distro. Which one?

Also a print out of /etc/X11/xorg.conf would be nice

and if your distro is RPM based a rpm -qa |grep nvidia would help.
