720p on panasonic ae900u not working with mythdora 3.2

I was able to get a perfect 720p display when I used ubuntu dapper but when I changed to mythdora 3.2 (which is based on fc5) I can’t get a modeline that will correctly display.  For some reason every modeline I try make the bottom bar not show on the screen.  If I move the mouse down the screen scrolls and I can see the bar.  I have tried every modeline I could find.  Still working on it but can’t seem to find a modeline that will work so far.  The projector always says 720wide but it just doesn’t show correctly.

Mythtv todo list

  1. Check to make sure xvmc is working and hd programs do not shutter
  2. Get digital audio working
  3. install hdhomerun
  4. work on getting svideo working to tv
  5. put another gig in the frontend so it has a total of 2 gig
  6. purchase another am2 motherboard and processor setup as a backend
  7. tweak nvidia for performance (coolbits,etc)
  8. correct res for mythdora
  9. options in xorg.conf
  10. program pronto or buy mce remote
  11. /usr/local/pvr locations of scripts in mythdora
  12. Try a few of the options that are commented out in the xorg.conf file
  13. Hopefully I can get cpu usage down to 20% when playing back hd content
  14. adjust modeline to try to get cpu usage down.

Ok if that is too obscure: Go into Setup -> TV Settings -> Playback. Set the prefered decoder to libmpeg2, the deinterlace option should be set to One Field.

Optical output on the mythbox is working

Well that was to easy.  Just had to unmute the optical interface in alsamixer and then enable digital pass-thru in mythtv.  Now on to getting the resolution on the panasonic correct for hd resolution.  It is very close.  I hope to get that later today.

One step closer to a perfect mythtv box

I finally figured out I had some bad memory so I returned to bestbuy and got another 1 gig.  This time all 2 gig of memory works no problem.  I also figured out what was causing my system load to stay above 1 all of the time.  Now the myth box will reboot (not hang on shutdown or reboot) and has a load of 0 most of the time.  Now to get digital audio working tonight and get my pronto remote setup again so it will control the myth box and my onkyo reciever.  Probably will have it control the projector, tv and dvd player also.  I hope to find out if the mythbox can play back hd content just as good as my stb from charter.  It may be able to.  I was thinking that I would have to get a dual core processor but I may just have enough in the 3500 without xvmc to do it.

Think mythdora is the one I will be using right now

Today I finally got around to fiddling around with mythdora on he athlon 3500. Had some problems at first but think it was due to charter maybe changing some things with qam256 on our cable. I moved over to qam64 and scanned and got everything I should have and was happy. Put the pvr500mce back in the box and made sure all 4 tuners worked and then put the avermedia a180 back in and made sure that worked. All cards are working fine together. Running a final mythfilldatabase and then I will start to load test recording and probably move that box back out to the projector so I can start tweaking xorg for the panasonic ae900u and get ready for some of the great hd shows coming up soon.

So far mythdora seems to be doing everything I want it to do

I may have to stick with mythdora.  It just works.  I have made a few additions like phpmyadmin and freenx but the box just works.  I love it.  I plan to put a new hard drive in my main mythbox tonight and build it from scratch using mythdora.

Well it has been awhile since I have posted anything on mythtv

I finally broke down and tried another distro. This time I tried mythdora. It is based on fedora core. Guess what, 45 minutes after downloading I have the hdhomerun scanning and I can watch tv from mythtv. I plan on rebuilding my main myth box that is currently ubuntu dapper right now. I was so happy to see the hdhomerun work. I can’t wait to work on this over the long weekend. Hope it all goes as smooth as my test box went. May end up making this slower test box a slave backend and then rebuild the master backend later this weekend.
