MythTV Errors

[RadiationHazard]

Ok, so i have mythbuntu. and when i try to start up mythtv it starts up fine but when i select watch tv it says

MythTV is alread using all available iputs for the channel you selected. If you want to watch an in-progress recording, selcet one for the play back menu. If you want to watch live TV, cancel one of the in-progress recordings from the delete menu.

i've never used this before now so i don't know what it's wanting me to do...

Make sure you have configured your tuners in mythtv-setup, as well as attatched them to a video source

It would help to know a bit about your setup. What version of Mythbuntu? What capture card?

First step is noted above, run mythtv-setup and verify everything. You may want to try a reboot as well...I have had my capture card lock up once in a while.

[RadiationHazard]

i don't even know what a capture card is?
and how when i set it up how should i do that?
sorry i'm confused...

[RadiationHazard]

oh and i'm using version 7.10

Maybe MythTV is not for you... A capture/tuner card is what allows you to watch TV: The main purpose of MythTV.
You'll need one of these, and you'll need to set it up correctly before mythtv is of any use

[RadiationHazard]

well is there anything like mythtv that doesn't need a capture card or anything?

[Calash]

The capture card is what takes your TV signal and turns it into something the computer can work with. This is usually from a coax cable that comes out of your wall and feeds into the cable box or TV.

Is there a place on your computer where you can connect the Cable TV cord from the wall? If not, then you will need to buy a card to do this for you.

You can use mythtv just for viewing videos that you have already recorded/downloaded/ripped. But if you want to watch Tv with it you will need a capture card.
