I attempted an upgrade over the weekend, but ended up rolling it back.
Kudos to the myth devs that created the backup and restore scripts!
I'm still on v30 with Schedules Direct DataDirect and a cron job to run
mythfilldatabase. To get to v31 and the new xmltv grabber, I decided to
do the XMLTV upgrade now, followed by an upgrade to v31, say, a week
later. I chose this path since it appears that v31 would force the same
upgrade of XMLTV, and I wanted to decouple these two things. If I
approached this incorrectly, please let me know.
I ran the xmltv install, then followed the wiki to configure the sqlite
grabber. This all appeared to work, as I was able to see like 1,000 rows
of channel data in the sqlite database. As indicated in this thread, I
created a simple way to set the right channels as "selected".
After that, I went into mythtv-setup, channel editor, and deleted all my
channels. I only have one source that's by HDHR.
Then, I added a new video source that matches the name of the grabber
config, set this up as Multinational, and done.
Then I went into the other setup screen where I map the video source to my
HDHR tuners. Forget the name of that one. Capture cards?
After this, I ran mythfilldatabase. Looking at mythweb, I could see it
populated the channels back into the database, but I am pretty sure it put
in more than the ones I marked as "selected" in the Sqlite database
Strange. The listing started to appear, but VERY slowly.
Mytfilldatabase ran for like 4+ hours, and since I was getting close to the
time I needed to finish or bail out, I killed it. I then tried running the
script that does 3 days at a time, and this ran to full completion right
away, but never fully populated my listings. I still had major gaps in the
listings. Some were there and some never showed up.
Any advice before I give this another go this coming weekend? Is my
strategy flawed? Did I miss a step? How best to run mythfilldatabase so
that it doesn't take all day? Is it the 3 days at a time script?
Larry
