In previous releases of Mythtv, I was using xine to play DVDs and the deinterlace control (Toggle Interleave) was the letter "i" key.

With Mythtv 0.20, we are using the internal Myth player to play DVDs, correct?
Is there a control for deinterlace when watching DVDs with mythtv 0.20?

Apprecited!

Check the optical disk setup screens to be sure which player you're using. The DB variable name changed and it defaults to the MythTV builtin player which has serious problems with navigation.

If it's xine then "i" should still work. If it is and it doesn't, check that your /home/mythtv/.xine/keymap file still says:
Code:
# interlaced mode toggle
ToggleInterleave {
        key = i
        modifier = none
}

I think you read my question too fast. I'm not asking about xine.

With Mythtv 0.20, the default player for dvds is the internal Myth player, correct?

Isn't there a key control for deinterlace for the internal Myth player?

Yeah. Sorry about that. I don't think there is one. It may use the general TV Playback settings or have something under the optical disk settings.

BTW - I don't recommend the internal player for this. It's got some really nasty problems with navigation. Trying to skip forward or fast forward when playing a disk will send it into low earth orbit (if you try this, be sure you've got a way to kill the front end remotely first). I've been telling folks to switch back to xine for the time being.

Ah, thanks for the info!

I was wondering how to switch back to xine for dvds, in fact. (I had all the LIRC key bindings set up nicely for xine in R5D1.)
Are the switchback steps easy? :?:

Easy as falling off a log. You just enter the xine command to use in a text box.

I use:
Code:
xine -pfhq --auto-scan dvd

OK, for future reference the menu path is: Utilities/Setup -> Setup -> Media Settings -> DVD Settings -> Play Settings -> Page 1

Use the setting from my previous post there, on the Page 2 use the same but say "vcd" rather than "dvd".

Thanks tjc!

I LOVE "drunken monkey" directions! It removes all ambiguities, which is very necessary for people trying to learn Linux by example.

Best wishes!

Well hopefully at some point people start exploring, noticing patterns, and putting things together in their heads. It's amazing to me how many folks never get beyond the "magical incantation" stage, which means they often do inappropriate things out of superstition.

Does it matter if there is a "://" after the "dvd" or not? Example:
Code:
xine -pfhq --no-splash --auto-scan dvd://

I've seen it both ways and it's a bit confusing when one is trying to learn Linux by example. I need to know if it matters.

Also, I just noted that my VCD setting line was
Code:
xine --pfhq --no-splash --auto-scan cd://

Is the doubledash before th pfhq wrong?

Trying to learn right from wrong...

You don't want a -- before the single letter options. Linux/GNU command line conventions short (single character) options look like "-X" or if there are multiple together "-XYZ" (equalivalent to "-X -Y -Z"), long options look like "--long-option".

Also you don't want the //: with --auto-scan, the argument following it is a plugin name, like "DVD", or "VCD". Either "man xine" or "xine --help" will show you more information.

While this was certainly true for Knoppmyth, I'm now using the internal player on another Myth distribution that contains the latest Nvidia drivers and I don't have any of the "really nasty" bugs that I experienced under Knoppmyth.

I'm not saying this to knock Knoppmyth I just don't want people to write off the Internal player too soon. It does have some nice features that Xine lacks and it integrats much easier / nicer with the rest of Myth. It's also more wife friendly.

While I don't recommend it yet for Knoppmyth do keep an eye on it in the future. Also, if anyone is brave enough to install the latest Nvidia drivers under Knoppmyth it would be interesting to see if some of the "bugs" in the Internal player go away.
