HD Capture requires very minimal processing power. You should be fine for that. You can also set auto-transcoding, not sure what details you would want to use though as I don't transcode anything. <br><br><div><span class="gmail_quote">

Hello all, as they say on the radio: First time poster, long time reader.<br><br>I am in the process of setting up my first mythbox. Here are the relevant<br>specs:<br><br>Intel Motherboard with NO AGP or PCI-E slots<br>
2.2Ghz Pentium4 Northwood<br>1024MB PC2700 SDRAM<br>(2) 80GB PATA133 HDD, each on its own IDE channel<br>Air2PC rev 0.2 "ebay special" ATSC card<br><br>Video card: still gathering information, leaning toward the Nvidia FX5200
<br>PCI video card (fanless)<br><br>I've been able to test the Air2PC ATSC card under windows with the<br>included software (just got it last nite), and it works fine for SD<br>content. I get black screens when I try to view a HDTV stream, but since
<br>I'm still using the onboard video, this is most assuredly the culprit. I<br>will attempt a basic myth install tonite after I try to get the drivers<br>installed in Linux. Had a question in the meantime.<br><br>Currently I am not interested in viewing HDTV at its native resolution.
<br>Plus the up front costs are still a bit too steep for me, at least to view<br>LiveTV.<br><br>I'm working with a two system setup, both machines have identical specs on<br>the motherboard, CPU and RAM. The frontend will eventually have a PCI
<br>FX5200 video card (no AGP available on these boards).<br><br>I was wondering if it was possible for the linux drivers to capture/record<br>the HDTV content for transcoding purposes, even if the capturing machine<br>would be incapable of actually playing these HDTV files on its own? I
<br>would think with a frontend/backend system, for strict ATSC capturing the<br>backend shouldn't need much horsepower to actually save the stream, since<br>it will not actually view the content. Feel free to correct me on this.
<br><br>I'm looking for something that looks reasonable on a regular 27" analogue<br>CRT television (S-Video) after some modest transcoding to smaller<br>resolution H.264, Xvid, or MPEG2 for later viewing. My local PBS station
<br>has both HDTV and SD subchannels broadcasting, but they do not always<br>simulcast the same content. Sometimes I want to pull a program from the<br>HDTV stream, other times the SD.<br><br>Does anybody out there have experience with this (or any other) type of
<br>ATSC card that allows the capture of HDTV streams, especially if the<br>capturing machine cannot *view* the streams natively?<br><br>A better question: Is there any way to just scale down the resolution on<br>the fly so that HDTV streams could be viewed (albeit only at 640x480
<br>S-Video resolution) using the Live TV feature?<br><br>I'd like the SD channels available for LiveTV capability, but I still want<br>the HDTV channels available to record, even if I cannot view them live.<br>So far the documentation I've found on this is a bit fuzzy on how to
<br>accomplish this.<br><br>Thanks in advance for any comments.<br><br><br><br><br>____________________________________________________________________________________<br>Be a better Heartthrob. Get better relationship answers from someone who knows. Yahoo! Answers - Check it out.
