Gotta say I love my Mythtv setup. Server running Mythbuntu 11.0 with a Hauppauge 2250 and 1250 for a total of 3 tuners for strictly OTA recording. Recording setup using Mythweb.

I have a roof mounted CM 4221 pointed at the US receiving 30 channels including a few Canadian channels off the back.

Front end is provided by 2X PS3 in the house using PS3 Mediaserver. Additional entrertainment is provided by Netflix US via unblock-us.

I was using Sagetv on Windows Home Server 2011 but wanted to go back to Linux for a server as I had already dabbled enough that I enjoy the torture/experience that Linux gives.

@Roger1818are you saying there is a plugin that will remove commercials and resplice the recordings without transcoding that I can view on my PS3?.

Add Channels Mythv

Hi,

I need to manually add channels 67_2 WBBZDT2 and 67_3 WBBZDT3 into Mythtv. I am stumped as to what to input for the channel info. These channels worked fine under Sagetv so I know they are tuneable by my tuner cards.

On page 3 of the channel editor when adding the channels I put 1672 and 1673 respectively on the top line "channel or frequency id"

I am subscribed to Schedules Direct and I do not get any guide data for these 2 channels and all attempts to record on these two channels fail.

Any help would be appreciated.

It isn't a plugin, but the built in MythTranscode. Just make sure the Lossless box is checked in the setup. I don't recommend using MythTranscode in any other way as it has only caused me grief in the past.

The procedure to remove commercials is:
  1. Edit the recording (E while watching) to set the cut-points (you can copy them from the comflagging (Z or END), but I like to verify them after).
  2. transcode the recording.
Make sure the recording doesn't have a bookmark while you are transcoding as I have found it will cause problems. YMMV.

There is a way to automate this, but I don't trust MythComflag enough to permanently delete the commercials without verifying the cut points.

roger, you can set it to keep the original copy after transcoding. It adds a .tmp to the end of the original file and it stays in the same directory. If the commercial removal isn't up to your satisfaction, you still have the original and can simply delete the new one, and then remove the .tmp from the original. The database still works after doing this. You just have to remember to go and manually remove the .tmp files or you will have two copies of everything.

DM,

I would do a full channel scan and delete anything you don't want/need. Then edit the new channels and put in the correct xmltvid. The best way to get the correct id is to go to the tv listings on zap2it dot com, put in your postal code (or a zip code reasonably close to the transmitter) and find the channel, then hover the mouse pointer over the channel name in the guide. The link will have a 5 digit stnNum field, which is the xmltvid. Put that in the channel editor, save the changes, make sure you have the channel selected in your Schedules Direct lineup, and then run mythfilldatabase and you should get the correct listings.

To answer my own question. I finally solved the issue by using the DVB-APPS tools and performing a scan.

I then used the channels.conf in the channel editor and the 2 missing channels are now useable.

I forgot to ask what version of MythTV you are using. There were some issues with the channel scanner a while back, but I think they have been fixed in recent builds. I am always running close to current code, so it's hard to recall when things were broken and/or fixed.

dynomac: I recommend Handbrake to transcode recordings for long term storage.

I used to use mencoder but you're right it's quite outdated. I switched to handbrake and find it does a much better job. It's got a good CLI (Command Line) version which makes it easy to write scripts to handle all the types of custom inverse-telecine/de-interlacing options you might want. Like mencoder it uses the x264 codec but also uses the more modern container formats like .mp4 and .mkv instead of .avi.

One nice thing about handbrake is it will automatically crop out the black bars (letter and pillar boxes). One issue I have had though is some of TVO's UK programming is window-boxed with a 14:9 aspect ratio. Handbrake does the right thing and will remove all the black bars and MythVideo will play the resulting file just fine. The issue is if I then try to use MythArchive to put the video on a DVD, it will stretch it to 16:9 (distorting the picture) when it should be either letter boxing it to 4:3 or pillarboxing it to 16:9.

Any suggestions for fixing this?

Ug. Just read that one of the lead developers of mythtv has left to create a fork called torc. Hopefully this won't thin the developer resources too much.

It will be interesting to see what transpires of this. There is some speculation that this could just be a temporary fork for him/them to start working on 0.26 before 0.25 is released.

A script to scrape the CBC website for schedule info for mythtv

Hello all,

I've written a little python script to scrape the CBC web site for scheduling information and put the results in to an xmltv/mythfilldatabase compatible form. You use it like this:

# ./scraper 2012/05/21 > sched_20120521.xml
# mythfilldatabase --update --file 1 sched_20120521.xml

Since I rely on the PSIP info for my EPG, and CBC does not provide, this allows me to get CBC scheduling.

Would this be of interest to anyone - I would be happy to share it - or is there a better thread to discuss this?

If you are interested and grabbing a copy now, surf to newmovies.walma.org and right-click to download scraper.py. It is very rough and does no input sanatizing or exception catching, so use it carefully. It also depends on "beautiful soup" for html parsing, which, if you are using some flavour of linux, should be available through your package manager. There are some comments in the code which will give some hints to getting it working.

Mike
