M2NPV-VM for 1080I out?

[MattHelm]

Would the onboard video of this motherboard be able to do 1080I output while recoding with a HDhomerun? I plan on a 3600+ CPU.


Thanks,

Some people say they can, others say no. I certainly wouldn't plan on it. In my opinion, if onboard graphics worked for HD output, then that would be the recommendation by pretty much everyone here and no video cards would be recommend. My 6600 and 7300GS can barely handle outputting at 720P in overlay. I can't imagine this working reliably.

I have this board with 3800x2 ee; I downloaded some 1080i content--> forget 1080i with vmr9, the 6150 can't handle it, 720p was fine. 1080i with overlay was great though. The vmr9 problem has little to do with the cpu, as cpu usage was still low in vmr9, even though it was stuttering like crazy.

for reference, even my sempron 3000 can do 1080i mpeg2 smoothly in placeshifter on my lan (which I believe is entirely software rendered in overlay).

To clarify,

This board with a single core Athalon XP 3500 can decode the 1080i just fine, so long as the output to the display is 720p.

Crystal clear and smooth using nvidia drivers 93.71, nvidia video decoder, ac3, vmr9, and disabling the sage splitter.

I can do 1080i & 720P just fine with Overlay, forget VMR9. I have a dual core AMD 3800+.

PureVideo decoders don't make VMR9 possible on the 6150 either with HD output to 1080. I'm currently using CyberLink decoders just cause.

robertmcox: i also output 1280x720p; I don't see how you are running it smoothly in vmr9? i have 3800 x2 running the purevideo codec with same driver 93.71, vmr9 with fse, result with mpeg2 1080i: not smooth at all....which would suggest to me if it's perfect for you, there is a huge difference somewhere. What are your settings for the deinterlacing in the purevideo codec?

thanks,
Ben

yes, Im curious about this myself. I was going to try to run at 720P today and see if it improves VMR9 output. But I'm not sure my circa 2000 Mitsu rear projection CRT HDTV can accept anything from the PC but 1080 . With 1080 output, VMR9 is stuttery and the interface is slow.

also, what do you mean, robertmcox, by "disabling the sage splitter"? is that something in the graph? maybe that's the key.

[MattHelm]

Well, This system is up and running. 1080i output is great, no stutter at all. Matter of fact, only problem I had, was you HAD to us the TV's HDMI input to get 1080i. After that , all is working great. Only using MPEG2 data though.

Oh, take that back, slight problem. Takes FOREVER to start playback (5-10 seconds). This isn't tuning, this is starting playback on a recorded show. Anyone know why that might be?

[robertmcox]

Sorry for the delay in response...

...I set the display out resolution to 720p, connected with DVI to HDMI to 720p display. Set nvidia to preferred decoder, configured ac3filter to normalize volume so dvds w/ ac3 have the same volume level. I used radlight to pump up ac3filter's merit above nvidia audio. I then unregistered the sagetv mpeg splitter so that the nvidia splitter is instead used. In sage, chose vmr9, default, default, default, default, default, all the way down. You have to alt-f4 sage, then reopen it for the fse to take effect.

Cystal clear, smooth, fraps shows 60 fps on 1080i. Input source is hdhomerun with 2 x QAM from Time Warner, A180 with antenna, and a PVR-250 from the cable box. Also have comskip running in the background doing 2 shows at a time. All this against a Seagate Barracuda 16MB 7200 SATA2 drive sitting in an enclosure connected via USB; system drive is used for OS and for being a "file server" for the rest of the network.

To make DVDs playback, I had to choose nvidia decoder, default, default, default, all the way down. Otherwise, it was choppy with no sound.

HTH

Loving my Sage system!

So to clarify, you are using MPEG2 data SD source with 1080i display output? Or is it HD MPEG2 1080i source with 1080i output?

I haven't encountered the forever to start playback issue.

1080i (or anything else a HDHomerun can receive, NO analog) in and 1080i out. No stutter, and that was recording 2 1080i and playing back one of them.

At first I thought it was the HDHomerun tuner. I had heard it took a long time to tune, but then I went to playback one of the recordings, and it also took a while to start playing. I'm using a SAMSUNG SpinPoint T Series HD501LJ 500GB 7200 RPM SATA 3.0Gb/s Hard Drive, as I'd heard it was quiet. Could this be the problem? Everything esle about this system is VERY fast. (Even booting, which would make the HD ok.)

FWIW, I use the same drive and a HDHR, I really don't have a long delay tuning channels or with videos starting. 2 maybe 3 seconds.
