KWorld ub435-q v2 QAM patch request - Please sir

[Jaggy]

In the past most sluggish UI comment have seemed to come back to the directx runtime not being installed or not working properly, there is a warning in settings & log messages if it isn't working though.

FWIW I got exactly what you meant the first time; you want to use your card in NPVR precisely because it does all recording in a service.

By the way, seeing someone actually put the words "Please sir" in a qam patch request makes me smile every time.

Regarding the sluggish UI, have you confirmed that you have installed the latest DirectX 9.0C runtime update? Not having the runtime updated, or having a very old video card that doesn't support certain directx features will make the UI slow as it has to render it all in software. (yeah, what Jaggy said!)

A different Video Renderer might help. Have you tried VMR9 FSE?

I'm still laughing. Actually, I meant the main menu part of the UI (TV Guide, Recordings, Live TV, Search, Music, Videos). I guess the main window doesn't refresh if you have it behind other windows and it seems to take a second or more to refresh once brought back up when on the TV Guide. If I just click the app in taskbar, a blank screen appears. I have to mouse over the window to get the blank screen to refresh. The lag is almost nonexistent now, so maybe it was just a fluke or the epg thing. I just finished the XMLTV for all the channels and it is much more responsive. I haven't been able to see anything at all in LIVE TV (and can care less), but I'll try changing the Video Renderer later to see if that fixes that. Didn't even think about that. Thanks.

Jaggy, Johnsonx42, Thank you. I will try the runtimes later. I think it was something else though, since it doesn't seem to be an issue so much anymore. I did the redistributable (whatever the latest was) in November when I reinstalled Windows. I'll know if it's the same when I go to download it.

That goes for Reddwarf, too.

I just browsed your post and responded accordingly to Graham's post :o, reading your original post I can see what you mean now that I know it

[ub435-q v2]

Thanks again. DirectX shown to be fully uptodate. So I'm good there. Like I said in the last reply, the UI issue seemed temporary. Anyway, I tried each renderer to see if that might help LiveTV, but is still not showing. I don't care if it does or not, but since others with the same problem may read this thread later, are there steps I should take to fix the Live TV not working, or is it expected with this tuner? I know other threads for this tuner and others mention LiveTV not working, and it seeming to end up unresolved. No biggie. I'm done for the night. Maybe. Thank you.

The usual steps to fix any problem are to try what isn't working and then post your logs so that we don't have to just take wild guesses, but in the case of LiveTV not working my first guess would be that you don't have a valid HD-capable MPEG-2 decoder selected on the decoders screen. If you have ffdshow selected, you have to whitelist NextPVR.exe in the ffdshow settings. You'd also need both MPEG-1 Layer-II and AC-3 audio decoders selected to get sound.

I don't know of any case where LiveTV just doesn't work for some particular tuner... if you can record a transport stream, then you can watch it live too.

I've been looking through so many forums for so many apps, who knows what or where or.... what was I gonna say? Oh, yeah. I tried different DECODERS this time. First, Cyberlink KWORLD (I guess proprietary, since they don't work in nPVR). Then I tried regular Power DVD 7 (Cyberlink [...] decoder (PDVD7)) which happens to be installed (OEM disc app). I applied those for all but following. For H.264: ffdshow DXVA Video Decoder, for E-AC3: ffdshow audio decoder. That did the trick. Thank you. I'm seeing 10-20% CPU in nPVR with LiveTV but no noticeable performance issues with normal tasks. NICE.

I was supposed to not come back to this tonight, and yet, here I am. I have a question. I hope I'm just missing something. If not, I'll be disappointed. Can I schedule programs in advance? Like 2-3 days in advance? How do I do that? Let's say I'm leaving town for the weekend and I want to record a game or The Oscars or something. How do I schedule that? The TV guide only seems to cover 3 hours. Is there a way to browse several days in advance? If there's a wiki, just point me to it. Sorry if this seems like a dumb question.

[johnsonx42]

For US ATSC/QAM you need only MPEG-2 Video, MPEG-1 Audio, and AC-3 Audio. The general recommendation is to leave decoder settings for video and audio types that you won't be using set to Disabled.

Pretty nice program, isn't it?
