Troubleshooting guide?

Can anyone provide a rough troubleshooting guide to get the HD5500 working?

It appears that the right drivers are loaded and the card is working.

Dtvscan returns no HDTV channels.

This card has information scattered around the internet on getting it
to work. PCHDTV, you guys need to provide better installation
instructions. I did see the post from the software contractor about the
difficulty of getting the card to work in the open source community.
However, PCHDTV should provide install help for a a set of Linux
distros on a clean install. If such info exists could someone point it out
to me.

Thanks.

DTVscan is broken with the latest drivers, because they don't provide signal strength on the 5500. Replace all occurrences of FE_READ_SIGNAL_STRENGTH with FE_READ_SNR and you should get channels.

This isn't a problem if you're using the PCHDTV drivers from the CD, only the drivers which come with later Linux kernels, or from the v4l-dvb site.

nybbler,

Thanks for your suggestion. I am already using the s/w from pchdtv.

Here is my setup:
Fedora 4 updated to 2.6.17-1.2142_FC4
PVR150 using atrpms drivers (working)
HD5500
Mythtv from atrpms (working with PVR150)
No other funky h/w or s/w installed on the system
Comcast (assuming QAM256 from numerous Google searches)

I do not need to get any video out of the card to a TV. Using XBMC for
playback (an awesome piece of software).

Installed drivers from pchdtv and rebooted.
System sees card and appears to correctly configure.

Run stock pchdtv dtvscan - nothing

Find post about changing QAM_AUTO to QAM_256 in dtvscan
(Do I need to do this? Why isn't this fixed in the s/w from pchdtv!?)
Run dtvscan - nothing

Find post about cx88-blackbird.ko conflict with other drivers.
Renamed module so it doesn't load (couldn't get the blacklist to work so
I renamed the file)

Run modified dtvscan - nothing

Fireup mythtvsetup and add capture card.
Perform scan of analog stations and card sees them.
* input signal to card works *
Perform htdv scan via mythtv - nothing

Fiddled with a cvs pull of dvb-apps. Still no joy.

So where do I go from here? The only thing I can say for sure is the
signal is reaching the card.

BTW, atrpms is an awesome way to get mythtv with a pvr150 running.
Upgrades are painless and the stuff just works. Hint hint to pchdtv.

Didn't realize you were using QAM. That's a bit trickier. Comcast strips the program and channel info from the broadcast streams, so even if you can receive the channel, dtvscan won't put out the proper info. MythTV should still find it, though. Make sure you're using the 'us-cable' or 'us-cable-high' frequency table. If you can get any over the air DTV channels on a regular antenna, try that too.

Will dtvscan output any msg saying it found a channel?

When I run it, it just shows the channel it is scanning. No indication
if there is a HD signal.

With Comcast, usually you'll get a line like
: :55.1:55:2:1

but it quickly gets partially or completely overwritten.

Well, since you are running on the main distro pcHDTV does support, Fedora Core, apparently you are too far from a basic setup for the info that is out there. How about starting with a dmesg output from a fresh boot and we can troubleshoot from there.

If I understand correctly you can record from the NTSC portion of the card but not the digital side? Did you set up a DVB input in MythTV to scan for channels on?

More details about what you have done to verify your steps along the way would be helpful.

I did see a post about cx88-blackbird conflict so I renamed it to prevent
loading. True?

Do I need to change QAM_AUTO to QAM_256 in the pchdtv's dtvscan src?

Performed a scan of analog in mythtv on the HD5500. It found the
same channels as my PVR150 but I never tried recording/viewing from it.
Wasn't sure if that would hose up the database when I removed the card from mythtv.

Thanks for your help.

Hey Meme -
Your dmesg doesn't include any messages from the cx88-dvb module. There should be a message about "registering frontend". Your lsmod shows it as loaded so I would like to see the output from dmesg for it.

You can also try dowloading the latest dvb-atsc-tools-1.0.4 from the downloads section. The biggest issue with the new HD5500 cards is some tune faster than others so we had to take the timeout higher. I also changed the code to scan for both QAM256 and QAM64 modulation types so you shouldn't need to change anything in those files.

Rusty,

I am beginning to think it is the card...

I asked about the channel listing for my area here:

http://www.pchdtv.com/forum/viewtopic.php?t=1178

So there are hdtv signals on the cable.

Send an e-mail to Jack at support _at_ pchdtv.com and he can work out an exchange/repair/replace arrangement with you. Can you get video off the s-video port into something like tv-time? or off the tv-tuner running a VCR on channel 3? (Not saying you have to test those, but it's a test point.)

Jack is sending a replacement. If I get a chance, I will try your idea.

Rusty,

No joy. Plugged in the new card and the same output from dtvscan.

Any ideas?

TIA
