Post subject:  HDPVR issues on LinHES 7 [SOLVED]
I dusted off the old MBE/FE and did a 7.02 install, then did a pacman -Syu to bring up to the latest. I'm at kernel 2.6.39-LINHES with latest Myth code as of yesterday.

i.e. core-testing/mythtv 0.24-21 (pvr) [installed]
A Homebrew PVR project


I have a DCT6414 III Cable box and a HDPVR. Which has worked pretty darn well in the past.

HDPVR:

I can cat /dev/video0 > test.ts and it works great on SD and HD channels.
I can mythchanger -c 992 and it works great.

The Issue:

The problem I'm having is the Mythbackend isn't even attempting to change channels. And when I go to watch TV, it doesnt trigger the HDPVR to start. I have "/usr/bin/mythchanger -c" as the channel change script. I even tried the old 6200ch for grins which also works from the command line, but doesnt work. Heck I even set the channel change script to /bin/true to just have it pick up and record, but the HDPVR never triggers. I've set both my starting channel and preset tuner channel to 992 in mythtv-settings.


Below is my debug output of mythbackend using -v channel. At .995 I selected watch TV. MBE never tries to change channel or trigger recording on the HDPVR.


Help a brother out? What am I missing?

Thx!

Bryan

I did a fresh install of 7.02, changed nothing upon install. It does the same thing. Wont trigger the HDPVR when I go to watch TV and wont attempt to change channels.

#cat /dev/video0 > test.ts
and
#mythchanger -c

works without a flaw from the command line...

Crud I hate figuring something all by my lonesome, sinking hours upon hours on insanity google searches that yield *zero* useful information... betcha all been there..

This one, it turns out was easy.. and all the clues are in my debug above..

It was a layer 8 issues for sure..

read this slowly:

IF YOU HAVE AN HDPVR, DO NOT PUT A CHANNEL IN THE PRESET TUNER TO CHANNEL SECTION IN MYTHTV-SETTINGS. LEAVE IT BLANK..

ok, off soapbox, there I said it...

...and durn it, it also cryptically (or not so cryptically) alludes to that same fact in the mythtv hdpvr wiki page. It says "You must leave Preset tuner to channel empty or LiveTV and channel changes will not work."

DUH.. [smacks head with hammer]

Anyway.. SOLVED! Fully upgraded 7.0.2 with pacman -Syu and updated pacman.conf for latest testing repositories and everything is hunky-dory.. Recording my Doctor Who marathon and happy as a lark on Kenel 2.6.39-LINHES.

Thanks Team!

great to hear. Been there done that. It's moments like these that you realize MythTV is a hobby not an end-user product.

No Joke.. I *love* the ability to watch TV *my* way. But when it doesn't work.. dude....

Now if it'd just be stable enough so my wife wouldn't break it every time she touches the control, I'd be happy. But that might be a bit much to ask.. She loves to channel surf (she refuses to use the guide :roll: :roll: :roll: :roll: ), and that doesn't work too well with a HDPVR..
