How about a central public read-only MySQL database instead? When you
think about it, it'd cut down on traffic a lot and it saves setting up
mythfilldatabase. Would have to have consistent uptime though. Anyone
think this is possible or am I just plucking?

Oh, I should've introduced myself as well a few weeks ago. I'm Sam
Hadley-Jones from Palmerston North (currently). I've been running a
KnoppMyth based mythbox for about a year now on a Shuttle SK43G just for
the media library. This week has seen a major upgrade with a new nvidia
6600, PVR-150, shuttle remote (PN31) and an extra 250GB SATA Seagate
drive. The drive was DOA though so it's being returned - that's the
second time I've had that happen from Super Cheap PC. Lesson learned -
if you're planning on an upgrade path for storage, start out installing
LVM, otherwise it's a nightmare if you don't have access to other
storage to swap partitions around on.

Does anyone else use torrents for grabbing US TV episodes? Currently I'm
just using (screened) btdownloadheadless which works well but a bit
awkward for adding torrents. Was thinking about making a web GUI in PHP
so I can add torrents while I'm procrastinating at work :) . Has this
already been done?


Sam.

That would be illegal, and thus shouldn't be talked about on a public
mailing list :-P

There are a couple. Torrentflux[1] is probably the most well known
one, and can use btdownload* as the backend. Azureus[2] also has a
Java-based web plugin.

Do you mean that whenever we brought up the EPG im myth it would go
offsite to a cntralised mysql server?

The difficulties IMHO outweigh the advantages:

1. speed (or lack thereof)

2. everything in mythtv is stored in the mysql database, not just the
EPG. I don't think there is currently any way of saying to mythtv "look
up my local network settings on localhost, but look up the epg on
another server".

3. uptime of both your own internet connection (adsl up and down all the time at my place), and the server's

4. single point of failure.

OTOH if you are talking about synchronising a central mysql server with
your local box, that still has problems. In fact it is the reason the
xmltv format was invented I guess.

mr.geek had a simple script that downloaded either the full sky listing,
or just the FTA stuff. It cannot be that hard.

If you want a system that is fully configurable as to channels
downloaded, and has info on "genre" included, see xmltvnz at
http://www.reven.co.nz . It is a c# screenscraper and works under linux
(using mono) or windows. It is actively developed as various websites
change their formats. It is however a little slow and a bit heavy on
memory usage.

for those interested in the format of the listings generated by xmltvnz,
here is a sample, just gathered:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tv SYSTEM "xmltv.dtd">
<tv generator-info-name="xmlTVNZ v2.3.4.4">
<channel id="01">
<display-name>TV1</display-name>
<icon src="http://www.gbpvr.com/logo/TV1.jpeg" />
</channel>
<channel id="02">
<display-name>TV2</display-name>
<icon src="http://www.gbpvr.com/logo/TV2.jpeg" />
</channel>
<channel id="07">
<display-name>Prime</display-name>
<icon src="http://www.gbpvr.com/logo/Prime.jpeg" />
</channel>
<channel id="03">
<display-name>TV3</display-name>
<icon src="http://www.gbpvr.com/logo/TV3.jpeg" />
</channel>

[snip]

<programme start="200603301605" stop="200603301635" channel="01">
<title>Bill's Food</title>
<desc>Bill is on a food magazine shoots where he reveals his personal approach to food styling and photography, and shares
his 20-minute midweek dinner ideas with us.</desc>
<category>General Entertainment</category>

<title>Te Karere</title>
<desc>Scott Morrison presents the latest news and current affairs in Te Reo Maori.</desc>
<category>News</category>
</programme>

[snip]

Note the "category" info, which i don't think any of the DVB solutions
provide.

also note that including tv3 generates a segfault for me, but choosing
to get the tv3 info from sky (option sky_tv3) works fine.

There is a handy web app for generating your command line here:

http://reven.co.nz/index.php?option=com_content&task=view&id=29&Itemid=46

It'll give you a good idea of the options available.

Also note that the memory and cpu usage problems I had were when
greedily grabbing 10 days worth of listings. (recommended is 5 days)

IIRC, mythfilldatabase does some cleanup work that you need even if
you're not using it to load EPG data.

It's in the stream, just not being parsed. Some of those unknown bits in
the hairy.geek.nz output are indeed catagories.

David Z mentioned a while back that the category information is in the
DVB EIT feed. Someone just needs to fix tv_grab_dvb to understand it.

Hey Sam!

Azureus has a web plugin that pretty much allows you to do anything that you can normally do. I
like the client a lot, although it can be a bit "heavy" and needs X to run (but you can still run
it "behind" mythfrontend). Make sure you use Sun's JRE (java VM) though, I used Blackdown first
and it tended to crash now and then. You can find azureus here: http://azureus.sourceforge.net
