Thanks for the info!<br><br>Looking at the datasheet I think it should be possible to use RGB.<br>As you say I'd need some 23ohm resistors in series with the load and a 75 ohm load...<br>I'd also need to set a bit in a register to enable the RGB as it's turned off by default, this shouldn't be too difficult to hack into ivtv.
<br>But yes 3 wires only! The CSYNC is already provided...<br><br>Cheers<br><br>Steve<br><br><br><div><span class="gmail_quote">On 18/06/07, <b class="gmail_sendername">ryan patterson</b> <<a href="mailto:ryan.goat@gmail.com">

<br>Folks,<br><br>I'm considering getting a PVR-<span id="st" name="st" class="st">350</span> instead of slogging away with trying to get native TV out... However before I splash the cash I have some questions:<br><br>
<br>1) How stable is the PVR-<span id="st" name="st" class="st">350</span> under Myth? I know on Windows GB-PVR it's been all but abandoned due to instability, restart problems etc etc. What's the situation with Linux?
</blockquote></span><div><br>Stability seems to be a mixed bag. Once I got it configured correctly, I used my pvr-<span id="st" name="st" class="st">350</span> for output for over a year with no problems. But after a kernel/x.org upgrade the driver started crashing all the time. I had to revert back to a previous config to get the functionality back. There is probably an updated driver available now.
<br><br>I think if you have it setup correctly the pvr-<span id="st" name="st" class="st">350</span> can be 100% stable. But it will probably take time and effort to get there.<br></div><span class="q"><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
2) The one thing lacking from the PVR-<span id="st" name="st" class="st">350</span> in my book is an RGB output...however looking at the specs for the TV chip (the SAA7127?) on board, it can produce the RGB signals. So it MAY be that I can do some fine brain surgery to add the 3 necessary wires. Has anyone tried this? Would anyone be prepared to take some high resolution piccies of both sides of the board so I can see how feasible it might be?
</blockquote></span><div><br>For the determined user I'm sure this is "possible." You might have to tell the chip to use the RGB output somehow, if it isn't enabled by default. I'm certain you will have to add more then three wires. There will need to be load resistors/capacitors on the line as well.
<br><br>Will you really gain anything from running RGB at the resolution the pvr-<span id="st" name="st" class="st">350</span> uses? I assume you are in PAL land if your standard definition TV has RGB input. If your TV is HD (even just extended definition like 480p) then a standard videocard is the way to go.
<br></div><span class="q"><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">3) How well does it work for non-MPEG2 output? Is the frame buffer up to the task of showing DVDs/DIVx etc?
</blockquote></span><div><br>The pvr-<span id="st" name="st" class="st">350</span>'s frame buffer produces a better picture then an nvidia/ati TV-out even when not using the hardware decoder. I watched avi's and .mpegs and it looked great. There was some vertical tearing that was noticeable but not distracting to me. But beware, there is a significant amount of overscan. Normal shows are not a problem if you miss some stuff on the edges but stuff with subtitles look out.
