Adding HVR 2250

[castlec]

All,

I'm looking for the correct way to add a new capture card.  I have an HVR 2250 dual tuner capture card.  The driver was just released and I have it working fine on a vanilla mythbuntu install.  I've been told that I need to create a new device template for it to function within LinuxMCE but I'm not sure what the template options need to be.  Is it necessary to write a wrapper for V4L devices?

I tried setting up the card in mythtv directly but when I click on the watch tv button in mce, I get a black screen. 

Thanks for your help,

Chris

To fully support the device in all modes, LMCE needs a card that can output MPEG streams. Is this the case with this card?

It is an ATSC device so the answer has to be yes.  Correct?  It does have mpeg 2/4 encoders.  Is there a program I can use to definitively test it if you can't answer from the info I have already given?

Thanks for the info Thom.  Assuming that pans out when I try it tonight, what would be the correct procedure?  What would be the procedure otherwise?

mplayer /dev/video0

mplayer doesn't like it

A mild change from my previous statement.... if I use /dev/dvb/adapter0/dvr0 mplayer just takes it.  If I do the same with VLC, it says that it is loading libdvdcss.

if this is a dvb card, why don't you use VDR?

if this is a dvb card, why don't you use VDR?

-Thom

The one and only answer to that is that I have no idea how to use it.  I take it there are advantages to the usage of it?  From what I read, I could see no compelling reason to use VDR.  Is the MCE integration better?  I gave it half of a shot on one install and got nothing out of it.  I figured I would have better luck with myth since I already knew how to use it. 

If I do use VDR, how do I make MCE happy with the unsupported card?

Thanks for your help,

under 0810, VDR would work much better with your card, as VDR supports these devices out of the box much simpler.

So the real reason I wasn't using VDR is that my card is ATSC which is only supported with a patch to VDR.  Are there plans to offer the patched version?

I went back to mythtv and got it working at the core.  It looks like the issue within myth was the playback profile.  If I use slim or normal, I get playback, otherwise, I get a blank screen.  Of course, I still don't know if there is anything I need to do for MCE or just myth.

Afterward, I enabled diskless MDs and did a PXE boot.  I noticed that the image starts myth-backend.  Also, I am unable to get streamed TV from the core.  Is this normal behavior and/or do I need to modify the image?
