@rpr,
Editing the myth code (then compiling/building/etc) is far beyond my limited Linux skills. Maybe someday...

My current thinking is to further enhance my Change Channel script by putting in a delay of a couple of seconds to let myth make its changes to the audio and video parameters, and then stuff my desired parameters into the card. But I need to somehow fork the CC script so it can return control to the mainline first, while leaving a remnant in stasis. I'm not sure how to do that, though there must be a way.

I just noticed something strange on my new myth box. When I upgraded my box I replaced everything except the tuner card. To do this I installed MythBuntu on the new system, giving it a new name figuring it was a bad idea to have two computers with the same name (even if temporarily). Once I had everything working, I copied the database and recordings to the new box, put in the tuner card to finish the setup.

Just today I noticed using mythWeb a bunch of references to my old system. For example, when checking the status I see:

Encoder Status
Encoder 1 is remote on mythtv-desktop (currently not connected).
Encoder 2 is remote on mythtv-desktop (currently not connected).
Encoder 5 is local on MythTv2 and is not recording.
Encoder 6 is local on MythTv2 and is not recording.

(mythtv-desktop was my old box and MythTv2 is the new one)

Also, when editing the settings of MythTv, it gives me a pull down to select either mythtv-desktop or MythTv2.

How do I get rid of these references to mythtv-desktop?

Thanks.

Or you could use it as a backend only...

Have a nice day!

@roger,
What's worked for me when I had a similar problem is to go into the Capture Card config page, (in backend setup), delete all tuner cards on all backends, and then add in your tuner cards again. That should delete the existing entries and create two new cards #1 and #2.

However, I'm not sure that this will eliminate the references to mythtv-desktop in the drop-down.

@nick,
Not a bad idea. I've been looking for an excuse to get a Zotac ZBOXHD or something like it. Mount it on the back of my Bravia. Other household members will never know it's there:-)
I wonder if it's too late to get an order in to Santa...

Yep, that will take care of the tuners...

He'll need to delete all entries in the settings table where the host name is the name of the old Myth box.

Something like

DELETE from settings where hostname = 'mythtv-desktop'

Have a nice day!

K1Y3M5 and Knight, thanks for the advice. I will do these when I have time and the box is not in use (tough combination to find ). It would probably be best to backup the database first just in case things go wrong.

To delete the entries in the settings table, I assume I need to first start the mysql command line interface?

The Zotac ZBOX is a good option as it has the Next Generation ION GPU.

Yep, something like

mysql -u mythtv -p
use mythconverg
DELETE from settings where hostname = 'mythtv-desktop'

The Zotac ZBOX is a good option as it has the Next Generation ION GPU.

It's also a lot easier to upgrade than a Zotac MAG (I have one and it's a pain to upgrade and you risk losing your warranty...). The Zbox is essentially a MAG with an ION 2 instead of an ION 1 chipset and more DIY-friendly...

Have a nice day!

I just noticed on Zotac's website that not all Zboxes have the Ion2 chipset. Some have Intel or even AMD (i.e. ATI) chipsets, so make sure you get one of the right ones.

[Knight]

Argh, not cool on their part to have done that... I knew some models had better memory but hadn't noticed they had started using other chipset (and it looks like other CPUs as well)...

BTW, if you get a Zbox you might have the same problem I had with my MAG, they ship a weird power plug with it that has a little wire that you must connect to the screw in the middle of the outlet to get the ground (like the old adapters people used to use in the past) instead of a normal three prong adapter...

To get it replaced you must contact Zotac which will then contact one of their distributor in Canada. I had to contact Zotac back because that distributor wanted me to ship them back the old cable (at my expense)... Zotac contacted them back and told them they did not have to do that but it was an hassle nonetheless...

Have a nice day!

Thanks again. I did both of these fixes last night and it worked like a charm. Not sure if I am seeing any benefits (it still takes a few seconds to load the list of recorded programs), but it certainly good to get rid of the garbage data.

is anyone capturing svideo off a satellite box? using a ir blaster to change the channels?

Which card are you using?

I would like to try with bell tv.

thanks

[Knight]

ClgShaft, I'm not doing this but what used to be the least trouble-free cards to do this were the PVR-150 cards...

They have been discontinued for a while though but you might still be able to get one (probably used though).

I don't remember if your motherboard has PCI ports though...

Nowadays people who want to do this but for HD use an Hauppauge HD PVR but this is not entirely trouble-free AFAIK...

For the HVR-2250 if you wish to have Analog you will most probably have to compile the drivers yourself since I doubt support for it is included in the ones that come with your Linux distribution.

Have a nice day!

Nick

[ClgShaft]

Thanks knight.

Since I have the 2250 I will try and compile the file to get analogue working. Do I need to do anything with the driver I have installed?

Looks like the hd pvr works hauppauge hd pvr
