Astounding MPG playback

[garymeds]

As opposed to the very well read 'disappointing mpg decoding' thread on the support forum, I thought i'd share (and backup ) my recent config.

This has given me amazing playback both on live tv and recorded mpg's - avi's and mkv files also looks great, although these (i found) are not as difficult to perfect.

Hope this gives someone searching some help and also, if anyone can suggest any improvements (although picture is near perfect at the moment), please do.

Thanks

What did you tweak in the PVR150 settings? I have always had a problem with audio & video going gradually out of sync on live tv unless I set GBPVR deinterlacing to "None" - I think it may be something to do with the PVR150 MPEG stream, as recorded (or timeshift) TV is fine.

Thanks - good idea to publish the success stories. It's helpful to see what works.

ah, the temporal filter setting is remove the blurring i found when using the PVR150 analogue composite inputs.

check this thread

i've never seen the audio and video lose synch - that's strange. you using updated 150 drivers and checked hauppauge forums?

overlay - vmr9 custom

which one? using pvrx2 right? overlay or vmr? fse?
it's all about the details...
i've gotten perfect picture from evr on my hd3450...only now getting vmr9fse to work right...evr worked out of the box..beautiful color too...

do movies adjust aspect correctly when set to 'letterbox'?
i always used anamorphic with nvidia...
have you tried the ati mpeg decoder? [avivo]

I read somehwere the http://www.cask-of-amontillado.com/pvr_tweak.html tool couldn't be used with the latest PVR-150 drivers (which I need for timestamp repair), could you edit your post to inlcude your PVR150 Driver Version?

it is usefull to tweak, but only with the procamp access on last tab..
the settings seem to stick even upon reboot so just set it and forget it..
also works for any card you can get to show up there..
[i used it for a hvr1600 also just fine..]

the other tabs don't refer to the proper areas for current drivers, but the procamp and encoder pages have all that's available anyways...so nothing really lost..[ok,maybe sound..but i think it's in there too] as always, YMMV

yes, i will check and prob update post with driver version seeing as theres a bit of interest!

they seem to, but i haven't tested thoroughly..

according to wikipedia : ATI's AVIVO is a technology still under development and as such will be continually upgraded via ATI's Catalyst series of drivers. Compared to NVIDIA PureVideo, AVIVO does not offer any actual decoding software like the PureVideo MPEG-2 decoder. It only allows decoder developers to utilize the DXVA API.

this outdated?

just a thought, wouldn't it be good if someone would write a GETMYSETTINGS.BAT/EXE and allow us to post them in a nice readable format!

I have often thought of that. It's something I can do, but really swamped at the moment. I'm sure it's something others can do too...
