Clever Tricks with MythTV (O'ReillyNet)

Here's an O'ReillyNet article on building a video recorder with MythTV. "The general advice is not to buy a TV card with its own remote. Apparently, this almost guarantees that you'll have difficulty making it work. The best way is to use an IRda keyboard and a programmable remote control that operates on a variety of frequencies. You train the remote from the keyboard, which will be useful also for web browsing or other activities you might consider later."

Happy New Year to All!

I would like to thank Linux for popularizing Opteron processors. And to Bill Gates, you suck! To Linus, Solaris is definitely not a joke.

Cheeers!

Happy New Year to All!

Gettin' started early, eh?

Being a little-or-no-alchohol type myself, I've been in system admin just a bit too long so that may change.....

Happy new year to all, including Bill Gates (Billy, I hope you get drunk and give Linus a big kiss!)

I guess I shoulda said "A Windows system admin...." maybe if I'd been a Linux system admin I wouldn't be thinking of it.

Isaac Richards and the rest of the contributors have created an incredible platform. I've only been using it since version 0.15, but this is one of the best examples of killer apps for Linux I've ever seen. Kudos to the MythTV team for excellent work during 2004 and here's to an even better 2005!

If you use equipment that has been verified to work you will have no issues. I have a Myth box setup using the Hauppage PVR-250 that is recommended and known to work and there are no issues with the remote.

PVR-350 here with the included remote working just fine. I think the author of this article needs to read the actual MythTV installation documentation, because he makes some assertions and some recommendations that are contradictory to those docs.

Does anyone know the status of the PVR 500? I'm waiting for it to be supported.

It seems the support is coming according to this thread:
http://www.poptix.net/ivtv/Dec-2004/threads.html#00371

I have ordered one myself.

The referenced discussion shows that they are in the preliminary
stages of writing a driver (looking a spec sheets) so it is not a certainty
that it will be supported at this point. Do you know if there has been any
additional progress?

The remote included with some ATI all-in-wonder cards works nicely out of the box; it acts as a USB keyboard.

Do the ATI AIW cards work with MythTV? The website says that they don't
but it looks like it is somewhat out of date.

I'm considering building one of these systems and I'd like to find a nice
capture card with at least stereo sound without having to connect to the
line in on the soundcard.

An card that supports ATSC would be nice too, though it appears there is
only one (HD-[23]000) and it doesn't do encoding of NTSC transmissions and
I can't figure out if it does audio capture.

The HD-[23]000 don't encode anything. For ATSC, they pass through the MPEG2 stream that's capture over-the-air, no audio device needed. For NTSC, they're frame-grabbers and for that you'll have to pass the audio to some capture device.

I'm still working out what I'll get to handle ATSC adequately. I prefer AMD (and want to run x86_64), but the mythtv-users list says Intel is far better for decoding that rich of an MPEG2 or MPEG4 (after transcoding) stream.

Ok, this is a verrry old article now so few people will read this, but on
the off chance anyone uses the search engine...

I've found more information about this. There are currently two hardware
options for digital TV on Linux.

The HD-3000 works under Linux and supports OTA (over the air) NTSC, but
just as a frame-grabber. Video encoding will have to be done in software.
Not sure how the audio works for it.

It also supports OTA ATSC and unencrypted digital cable. Since these are
already encoded as MPEG it just provides the stream to be written to disk
(just as you said).

However, if there are multiple sub-channels, it doesn't have the hardware
to split them apart so you end up pushing a lot of data over the bus.

There is also the Air2PC. It does not support analog TV, over the air or
otherwise, but it does support OTA ATSC and unencrypted digital cable. It
also splits sub channels so it is nicer on your system bus. Some people
are saying that it gets better reception than the HD-3000 but others
disagree.

What I would like to know is if a PVR-350 can handle MPEG2 input which was
not created by it, and if so, what resolutions? I would like to use the
TV-out to connect to a standard definition TV, but playing high definition
streams captured by another card.

If you get stuck setting up this sort of software have a look at PVR Guide - for help and how-to guides on setting up MythTV
