Re: [mythtv-users] record in HD, but watch in analog ?
Joshua, The 16:9 programs recorded in HD, how do you play them on analog TV (4:3) ? Do they play with black bars on top and bottom (just like watching DVDs on a 4:3 TV) ? Also, if I connect frontend to an HDTV (which has 16:9 aspect ratio .. Panny DLP) using svideo, will I see the HD program in 16:9 (if its recorded in native 16:9, say CSI, etc). Ofcourse, the quality will be downres'd to svideo, but is the 16:9 aspect ratio still preserved ? My main goal is to watch the HD programs in their native mode but sacrifice the HD quality right now. Once I've figured out what I need in the HD-frontend, I'll switch to HD output. But I still want to jump on the HD bandwagon. (It'll be better than watching taped shows on a vcr getting signals from a rooftop analog antenna ! the vcr is connected to a panny DLP tv .. talk about waste of resources ) Thanks Mudit On 5/9/05, Robert Tsai <[EMAIL PROTECTED]> wrote: > On Mon, May 09, 2005 at 03:56:07PM -0400, Joshua M.

Re: [mythtv-users] record in HD, but watch in analog ?
So which machine is downscaling ? frontend or backend ? My backend is going to be a sempron 3000+. Since I dont need much horsepower in the backend, I guess a sempron 3000+ should be ok (as per tomshardware.com mega cpu list, the sempron 3000+ is about 5-10% slower than athlon xp 3000+ for audio/video encoding purposes). My present frontend is going to be a sempron 2600+ box, with geforce mx440 with svideo out. This is a temp solution. My permanent frontend for the analog TV will be the media mvp (if I can get it to work). The media mvp has builtin mpeg decoder with svideo out. My main issue is if I watch HD recorded/live on analog TV, how much horsepower do I need to downres (and where ? front or back ?)

Re: [mythtv-users] record in HD, but watch in analog ?
My wonder is this downscaling of the HD, can a lower power machine play these HD recordings after the downscaling? So i guess the better question is - which takes more power Downscaling to 800x600 or 1024x768 or Outputing at 720p or 1080i On 5/9/05, Joshua M.

Yes, no problem. One of my frontends has an MX-4000 card using S-Video out. You won't get HD res, but you can display HD programs on an analog TV. Out of curiosity, do you have performance issues down-scaling 1080i or 720p content? Nope, no performance issues. Of course this particular frontend is a P4 2.8 w/1Meg cache so I probably wouldn't notice performance problems anyway. It isn't hyperthreaded, but I had no problems displaying 1080i or 720p (actually scaling 720p to 540p as my TV doesn't support 720p) back when I was using it with a 9A60 to convert VGA to component video. -- David HDTV frontend I'm working on (pictures, mythmon source) http://mythhd.info ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I have that exact setup at my house. My main frontend downstairs is a P4 3.06 that is also the master backend, and has a ivtv card connected to my Dish receiver for watching satellite channels. It is connected with svideo+spdif to my AV receiver and TV. Upstairs I have another front/backend combo with the pcHDTV in it that records OTA HDTV using my attic antenna (though sadly it's not fast enough to watch HD). Even on my 10 year old trinitron TV the HDTV recordings are still very noticeably better than anything I ever got even directly off my sat receiver, let alone through the capture card. I often sit in my home office and watch the HDTV recordings on my Linux workstation, because once you've watched real HD it's hard to go back. Hell even Family Guy looks better in HD! :) The only annoyance I've found so far is that some stations like to transmit 4:3 programs in a 16:9 signal with black bars and I'll have to manually adjust the aspect ratio on those to make it fill the screen. On the bright side, my local Fox station does this sometimes but keeps the Fox network logo off in the right hand side bar, so it doesn't obscure the video at all. :) -- Joshua M.
