Video in top left corner

[Graham]

NVPR gives me a naff display for Live TV and when playing recordings. The video is one quarter size and in the top left. Right clicking and fiddling with Aspect Ratio changes the size of the video but the display slows to about one frame per second. Tried several decoders (PDVD9, ffdshow, Mainconcept) ... problem persists.

Decoders are the same as in PVRX2. I can't reproduce the problem in PVRX2 ... it's good with VMR9 FSE and VMR9 Custom.

Video is Nvidia 8200.

yes, I get this too, was going to post on it later today. I get this with VMR9 on 1080i HD channels. SD channels are OK, and I'm pretty sure 720P HD channels are OK too but I wouldn't swear to it. The same channels are fine with EVR (but of course I'll be needing VMR for the negative aspect ratio modes).

This is an nvidia driver bug that occurs with VMR9, when hardware acceleration is enabled, and the aspect ratio is not set to 0,0,1,1. Try disabling hardware acceleration for now.

i get this on ati cards too and intel, so not just a nv bug...
tho mine also has 'noise' in black areas, but same behavior in positioning...odd results in windowed mode when playing with aspect, and can also be seen in fullscreen mode..
usually i can get it back to normal by just selcting aspect menu and opening submenu, but not selecting anything..
if i select auto, it shows problem again...

Thats odd. There is definitely an NVidia bug that can cause this, and is definitely the cause in the other thread (http://forums.gbpvr.com//showthread.php?...dow-aspect)), but you might be seeing something different.

If you F7 though the aspect ratios, does it come right?

[pBS]

nope..then auto leaves me a vertically squashed screen and skipping..

in fullscreen mode it seems to be ok,but still the aspect ratios aren't right..
hmm,looks like it's about the playback in vid library only...meaning other codecs being used..
you are still controlling what renderer is being used in vid lib. right?

[pBS]

yea, i'm getting strange codec entries when viewing from video library...

so that's probably where problem lies..tv seems ok on ati, no matter the decoder/renderer...
all about the video library and it's merit based playback..
btw, these are .mpg files..

also, am getting this in logs as playback starts....

even on video where everything's ok, right-clk and hover over 'aspect', now click it...goes to fill mode..without clicking a mode!
clicking on a mode does work and fixes it, but maybe something wrong in the menus?

[sub]

Ah, its a .mpg file, so you're at the mercy of whatever video decoder Windows picks. NPVR only uses its decoder selection code for file types it records (ie, .ts files).

Do you have the same problem playing .ts files?

[pBS]

ok, now getting it on livetv too...seems very random..codecs look ok...
and now it won't save my aac decoder choice...restarted and everything..
just keeps resetting it to disabled..

I reported this a long time ago during the beginning of testperiod. I never got it quite ok on XP and VMR9, 'cause if I found a SD decoder that gave correct aspect the H.264 decoder got it wrong, and using EVR the H.264 was correct but SD (ie. mpeg2) had this problem. One of my main reasons for taking the plunge to W7.
