Re: [mythtv-users] PS2 connected to a PVR 350
Thank you for all the answers. I see some confusion so I'll clarify my setup: I have a DLP projector with VGA, S-video and videocomposite inputs (BENQ PB6100). Previous discusion held on this mailing list suggested that I had to use the VGA input to get the best out of it. So I bought a (long/special/expensive/high quality) VGA cable and layed it through the wall and roof, and my plans were to have all the output passing through the VGA. So when my friends came with their PS2 and wanted to play with it, it seemed me the most natural thing to connect it to the PVR350 and leave the rest untouched. I see that I should, instead, forget about linux, ivtv and mythtv, turn off the PC and just run a dedicated cable from the PS2 to the projector... that's a bit sad but ok... :-) However, I'll try the suggested commands. This link instead: http://ivtv.writeme.ch/tiki-index.php?page=3DTvPassThrough returns a page cannot be found error...

You may still be able to use myth in this somehow: If the projector has an auto-sense input, you can have it normally use VGA, but when svideo signal shows up, use that. Then you can have a myth command that triggers the passthrough and effectively swaps game mode on and off. It would look like myth was still controlling things. Alternatively, if the projector has a remote to switch inputs, you could use an IR blaster from myth to perform the same task. But overall, it's effectively not connected to myth at all. SNES, NES, MAME, etc, can still be played from myth, however :-D However, I'll try the suggested commands.This link instead: http://ivtv.writeme.ch/tiki-index.php?page=3DTvPassThroughreturns a page cannot be found error...

Re: [mythtv-users] PS2 connected to a PVR 350
How do I select the input that is acquired by the PVR 350 ?I remember thare was a handy .pl program in the ivtv directory but it's not there any more :-(Is there a way to do it from within myth? hit C from within myth or use the command ivtvctl (I forget the parameters, but the help for that command makes it clear, use get inputs to find what they are and then use set inputs to select) I don't mean to be snide, but why would you want to run your PS2 through your PVR-350? Just hook it up right to the TV. I had stated it when I opened the thread:P.S. For those who forgot my setup and wonder why I want toconnect the PS2 to the mythbox, my mythbox has a DLP projectorconnected via a 10 meters special cable to the VGA output, and we wanted to play the games on the mega-screen :-)The projector is located on the roof on the opposite sideof the room, so it is not possible to connect the PS2 directlyto it... it has to be done via the mythbox Pretty sure it's not possible to get it to work with no delay. The 350 does hardware mpeg encoding, which no matter how you slice it, takes time. Even if you could get that delay down to miliseconds, it would still be noticable in games. You should be able to test it out without the playstation - try changing the channel on the cablebox / external tuner, if possible and see how long the change takes to propogate. or unplug the coax / composite input and see how long it takes. I think your best bet is an svideo switch. I'd love to see one that can be controlled by myth, I'd like to use that for dvd playing, swapping to live display for on demand, menus, etc. - Jeff ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

BTW, a good S-Video cable can go 50' (16m) without any problems. However, I definitely agree that taking the PS2 through the encoder card is a waste. Even if you get passthrough working in ivtv, you'll still have to get it working in Myth (which doesn't have any support for passthrough) or--more appropriately--in xawtv.

But if you're running an svideo cable all the way up to the projector anyway, why not just plug the game console into that directly? I can only assume that you don't have an svideo input on the projector, or you would have just used that from the get-go instead of an svideo converter. - jeff ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Re: [mythtv-users] PS2 connected to a PVR 350
Hello, I am continuing a thread that I started 50 days ago :-) It was about connecting a PS2 to a Mythbox via a PVR 350 the hardware encoder (also the decoder) have a delay of 1.5 to 2 secs you will always have this delay if you get the video from /dev/video0. ivtv-driver (/dev/video32 or 48; don't know exactly) that did direct pass-through with nearly zero-delay. You can try to watch this via mplayer. Maybe it works better. I've tried but I can only play /dev/video0 with mplayer, all other devices (video16/24/32/48) result in errors. Also, what I see in mplayer window is the last channel that was tuned by mythfrontend (if any), and NOT what is connected to the video composite input of the PVR350. How do I select the input that is acquired by the PVR 350 ? I remember thare was a handy .pl program in the ivtv directory but it's not there any more :-( Is there a way to do it from within myth? I don't mean to be snide, but why would you want to run your PS2 through your PVR-350? Just hook it up right to the TV. I had stated it when I opened the thread: P.S.

Kevin I want to do it too. Do you expect me tounplug mySVideo cable from the TV everytime I want to plug in my PS2? Shall Ihurk that entertainment center out of the way, crawl back there, and hope that I don't bend the pins again this time? Granted, I could just buy an svideo switch from Radio Shack, and have them both plugged in... But then my lazy @$$ has to get off the couch to switch between Myth and PS2.

Unfortunatelly the hardware encoder (also the decoder) have a delay of 1.5 to 2 secs. So IIRC you will always have this delay if you get the video from /dev/video0. But IIRC (again ;) ) there was another Videodevice provided by the ivtv-driver (/dev/video32 or 48; don't know exactly) that did direct pass-through with nearly zero-delay. You can try to watch this via mplayer. Maybe it works better. Anyone who knows better should correct me. I really don't know, if I remeber this correctly...
