WinTV HVR-850 again not working

I tried signing up for schedulesdirect.org and in the process of doing so had to rejig the MythTV setup to use these new listings.  While doing so, MythTV had me rescan for channels which now no longer appear.

I'm getting "Timed out, no signal" on channels that (rightfully) have no signal, but "Timed out, no channels" on those that previously worked.  I tried upping the timeouts to 10 & 12 seconds, but to no avail.  The machine hasn't been restarted, nor the device removed since it was working last.  There's no reason that I can see for MythTV to no longer be able to acquire these channels.

This is frustrating.  If you haven't already, DO NOT purchase the HVR-850 (or HVR-950 variant).  Get an HDHomeRun or similar and be happier.

WinTV HVR-850 finally working in Linux

 That was more painful than it needed to be.

The key to getting the HVR-850 (or HVR-950q, seem to be the same hardware) to work moderately well was placing the following in /etc/modprobe.d/xc5000.conf :

options xc5000 no_poweroff=1

This seems to allow the HVR-850 to do work without reloading itself randomly.  I'm using a stock Debian 2.6.32-4 kernel (from unstable at the moment) and the dvb-fe-xc5000-1.6.114.fw firmware file.  This loads the "xc5000" kernel module at startup and picks up the firmware from /lib/firmware without issue.

Another useful bit of information is that MythTV won't scan the ATSC channels properly unless the timeout was set to be 6 seconds or so (where the DVB card is configured in MythTV there's 2 places enter these timeouts as 6000 ms... set them large or Myth won't work in the Scan step).

Now that this has been done, I'm pleasantly surprised at how much info comes over EIT (the list of upcoming programs) ... so much so that I may not bother with schedulesdirect.org (though CityTV and OMNI really should start putting some usable info in their streams; I'm curious why they wouldn't).  I'm unhappily surprised at how much worse the tuner is than the Digiwave/Electronic Master DTV-5000 set top box I have.  It doesn't bring in nearly as many channels and the weaker of those it does seem intermittent.  I've been considering using an HDHomeRun as an alternative.  Doing so would also likely avoid the hassles I had with USB (not every USB 2.0 card likes the HVR-850) and also allow me to pick up more channels (as it seems the tuner in the HDHomeRun is much better than the WinTV tuners), and more channels simultaneously (since it has two tuners built-in).

I'm watching the results of these recordings on an HDX-1000 (through component video to my older Toshiba 34" CRT which still works well) as none of the computers I have are fast enough to decode & display the HD mpg stream.  They do seem to display well, in the end.

OTA HDTV

Finally got around to hooking up the outdoor antenna. Without any adjustment, the following come in clear:

2.1 2.2 2.3
4.1
5.1
7.1
9.1
11.1
17.1 17.2 17.3
23.1
25.1
29.1 29.2
36.1
41.1
44.1
49.1 49.2
57.1
64.1
66.1

Channel 49 is actually a little flaky and drops out. Perhaps turning the antenna a bit (tricky in the current setup) would help with this.

Next step: attempt to get the WinTV HVR 850 working with the MythTV setup.

Playing with console LJ client

Playing with a new (to me) console based posting client: charm.

If this works out well, I may actually get back to posting on this blog.

One of the annoyances when setting this up was the hashing of the password required a manual python run, during which the ljcharm.py could not be found. This was fixed with a setting of PYTHONPATH before the invocation.

git

I'm now attempting to work more seriously with git. Unfortunately, I have to interact with a CVS server at the same time (for final commits, etc). I still haven't found a really good way of doing this (initially with ideas from a blog entry). git-cvsimport works fine for pulling things down from CVS into the local git repository, but going in the other direction seems to require a separately checked-out tree and some annoying steps. I also tried an alternate approach where it's all in one directory, but that makes the git history much less useful and there's still weird conflicts after committing.

If anyone has a good way of working with a remote CVS server and local git repositories, I'm all ears.
