Getting a bit frustrated.

Ok so I got my 5500 last week and I still can't get it to work. I installed a fresh with FC6 2.18 Kernel. The NTSC seems to be working fine, apart from the audio. However I haven't been able to get any channels shown yet. When I saw about the signal problem with the 2.18 kernel I upgraded to 2.19, but still can't get dtvsignal to give me anything except 0. dtvscan does get me some stuff in qam, I got this for output:

Code:
      :      :74.1 :74: 2:1
      :      :76.1 :76: 2:1
      :      :77.1 :77: 2:1
      :      :78.1 :78: 2:1
      :      :79.1 :79: 2:1
      :      :80.1 :80: 2:1
      :      :81.1 :81: 2:1
      :      :82.1 :82: 2:1
      :      :83.1 :83: 2:1
      :      :84.1 :84: 2:1

And so on.
I did manage to get some video with getatsc using qam, but I can only get one channel and I can't seem to change it no matter what I use as an input for channel number. After a few tries though it will stop working even on that one channel and I will have to reboot to get it to work again.

Are you using the version of dtvscan that is specifically for the 2.6.18/2.6.19 kernels?

You can always grab the latest drivers from the linuxtv project by doing the following:
Code:
> yum install hg
> hg clone http://linuxtv.org/hg/v4l-dvb
> cd v4l-dvb
> make && make install


That will install Mercurial (hg) which you can use to pull down the latest driver code from linuxtv.org which you 'make' and then 'make install'. You will probably need to reboot to clear the old drivers out of memory.

From what you posted, it all looks like your card has installed correctly and should be working. Are you trying to get signals off an antenna (ATSC) or from digital cable (QAM)? You said you tried both and got something from QAM so I'm just slightly confused.

HTH,

Rusty

I tried both versions 1.0.4 and the 2.6.18 ones, only the dtvscan from the 2.6.18 gives me any output. Though neither dtvsignal does anything but display 000 for me.

I tried downloading the drivers from www.pchdtv.com and using those, but they wouldn't compile on my system.

Basically, the card does work in some respects, I can view normal analog television with tvtime (no sound, I'll worry about that later). If I do:

dtvsignal -q 74.1
Signal 000
getatsc -q 74.1 > /tmp/test.mpeg
ctrl+c
mplayer /tmp/test.mpeg
I will get New Hampshire Public television. I was very happy, then I tried some of the other channels:
getatsc -q 76.1 > /tmp/test.mpeg
New Hampshire Public television.
getatsc -q 77.1 > /tmp/test.mpeg
New Hampshire Public television.
getatsc -q 80.1 > /tmp/test.mpeg
New Hampshire Public television.
getatsc -q 84.1 > /tmp/test.mpeg
New Hampshire Public television.
getatsc -q 90.1 > /tmp/test.mpeg
New Hampshire Public television.
getatsc -q 121.1 > /tmp/test.mpeg
New Hampshire Public television.

After some number of getatsc commands, I stop getting anything in /tmp/test.mpeg and just get 0 file size and I have to reboot to make it work again.

I'll try those drivers when I get home, thanks.

I think with kernels 2.6.18 and 2.6.19 the signal level is not returned. At least that is what I see (Using antenna not cable.) The packages dtvsnr will return a SNR value which can give you an indication. Supposedly it will be fixed in 2.6.20 (at least when I read the change log for the .rc's I saw something.) My problem with the setup is I need a better antenna since the signal is sometimes just good enough.

I loaded the lastest drivers from linuxtv, everything seemed to go well. Except now, I appear to be missing some stuff:

Ok after a reinstall of FC6 it seems to be working better. However I do seem to have a tuning problem. I seem to be getting mixed channels and audio with getatsc. For instance I start it up on channel 85.1 and I see picture but the audio from a different channel, Then restarting it on the same channel might get me a different channel's video and anothers audio. Sometimes it does come up with the right audio for the video, but there is no consistancy for the channel, 74.1 may be PBS or E or something else.

edit:
I am using qam, these channels did scan with dtvscan and came up as qam 256, also if I use dtvsnr on the channel before I use getatsc there seems to be more consistancy with the channel I've asked for but not always.

edit 2:

Should I be concerned with these ?

getatsc simply grabs the entire transport stream which includes all video and audio for all "channels" broadcasting on a frequency. When you play back that file, your player is randomly grabbing a video and an audio channel to play. You need to use a player that allows you to specify what portions of the transport stream you want to see from your getatsc capture. These identifiers are known as PIDs (packet IDs) there is typically one video PID per channel and at least one audio PID but often times more.

mplayer has options for selecting the video and audio PIDs from a transport stream. Xine doesn't let you select them from a transport stream file, but they are in the channels.conf file for watching them live.

Bottom line is that getatsc is a debugging tool to make sure you can receive video independent of an external player. Once that is working, you should use a program that gives you more flexibility and control.

VLC works great, differing channels etc, saving the raw stream, or realtime transcoding it.

Code:
getatsc -q 81 | vlc -


Also, the .1 on the "74.1" channel doesn't work with getatsc. Took me a while to figure it out/get all the lingo down too.

Also, my getatsc does not change the channels, I have to use dtvsignal for that.

Got stuff working!!! Thanks for the help guys.

I seem to be having some play back issues, pretty bad performance. I seem to be missing something and can't use xvmc. My sound problems with NTSC was that funny connector, it doesn't want to stay plugged into the 5500.

I'll put up a list of channels I found for Comcast Boston when I get home. I found some streams, that I guess are temporary. I think the OnDemand movies come across as unencrypted QAM streams when other people order them.
