Incorrect channel numbers in MythTV

Share

We’ve had a HDHomeRun for a while now, and I’m very happy with it. One wart however was that Catherine was complaining that tuning for Go! didn’t work (an extra Win TV channel we get in this area). It was odd — it appeared in the channel guide, but recordings would end up recording ABC1 instead, and we couldn’t tune to the channel in the live TV interface either.

I fired up the channel editor in mythtv-setup, and the problem was actually pretty easy to solve… The channel scan had assigned channel number 2 to Go!, which is the same channel number as ABC1. It had also gotten the channel number for Win TV wrong, but we hadn’t noticed that because that wasn’t overlapping with another channel. The channel numbers seem arbitrary, given the database is also storing frequency and demultiplexing information, so the fix was as simple as just giving the various WIN channels the correct numbers (or I suspect any number that was unique) in mythtv-setup.

MythTV Chapter Ready: The Hard Way: Installing MythTV From Source

Share

The Hard Way: Installing MythTV From Source is now ready. In fact, its been ready for quite a while, but I have been trying to blog about the finished chapters in the right order, so it has been trapped in the queue. This chapter discusses how to compile MythTV from source code, which is useful if you’ve either had problems with a packaged version of MythTV, or want more control than you’ll get from packages.

The awesome Michael Carden did the review for this chapter once again.

How I plan on handling Ubuntu and Mythbuntu 9.04

Share

Ubuntu and Mythbuntu 9.04 have recently been released, and this makes some of the current content for the online MythTV book out of date. The way I plan on handling this is to keep going with the current version 8.10 content, and then update chapters to 9.04 later. This way I don’t delay the overall book because of the new release, and people who haven’t upgraded still have relevant content. For those using 9.04, the current content should be “close enough” to get you going. Please comment on this post if you see problems which are new to 9.04 so I can make a note of them.

MythTV Chapter Ready: The Hard Way: Installing Ubuntu

Share

The next chapter, The Hard Way: Installing Ubuntu is now ready. This chapter took a lot longer than I wanted because I was distracted by some stuff in my personal life, but I am hoping that the authoring process is now back on track. This chapter covers how to install Ubuntu so that you can setup your own MythTV system exactly how you’d like it. That’s also the way to go if you’re using an existing Ubuntu system and just adding MythTV to it.

Thanks to Michael Carden for yet another excellent chapter review.

MythTV Chapter Ready: The Easy Way: Installing MythBuntu

Share

The The Easy Way: Installing MythBuntu chapter is now ready. This chapter provides an overview of a basic MythBuntu installation, which is something which wasn’t covered at all in Practical MythTV, as MythBuntu wasn’t ready at the time. MythBuntu provides a simple installation and configuration option for those people who want to build a new MythTV system from scratch, and want to hide the normal Ubuntu install.

Thanks to Michael Carden and Jost Stewart for their reviews of this chapter, as well as Paul Wayper for his comments.
