Hardware acceleration on USB-DVBT
Hi guys, it's been a while, so please bare with me
I've got a Yuan USB DVB tuner, I think it's a PD300 Mini.
Anyway, the video is constantly dropping frames, and if i go into info in the setup, it says "Video Acceleration - Not in use". This upsets me a great deal.
Specs are as follows:
AMD64 3200+
2.5GB RAM
Nvidia 7900GS
Also, the program says it's using the YUY2 video format. Not sure if this has anything to do with it.
Also, after trying to do some research on the matter, I've discovered there are no BDA drivers for this device, which also upsets me, coz i can't use a generic other program with it.
Thanks in advance! Sorry if i've left something out.

So what windows do you have?
Have you run dxdiag?

Thank you for your speedy reply NooNoo. Unfortunately I don't have internet at work so i can't reply so fast.
Anyway, I'm on XP, latest service pack, etc, fully updated. Dxdiag tells me all is good - is there something I should be looking for?

Yuan is out of business.
That is page 3 of the thread - look at page 1.

This page still works
I suggest you click support and contact them asking for the software to configure the stick. I suggest you tell them about the video hardware acceleration message and ask them how to make it use acceleration.. Of course, if you have that plugged into a usb 1.1 socket, the frame drop will happen regardless... usb 1.1 is a bit slow.

well it works OK when i close EVERY other open application so i'm pretty sure USB isn't the issue. Thanks for the advice NooNoo, will just have to see what happens now.

Wait... you have other apps open?
Which apps? This stick works because the processor is doing all the work...

Ummm. Utorrent and msn messenger. Oh and chrome. But I usually close chrome when i've got it open, otherwise it's impossible to watch.
Yeah i thought so, being USB and all, which is why I'd love to have hardware acceleration going, coz i read some other's reports that it drops CPU usage by about 40%.

May I suggest you get rid of utorrent.

Well that seems to sort it out, it's just annoying to not be able to run *anything* else while i've got it open, and when i could be using this magical hardware acceleration.

have a look in your video card properties... and run dxdiag to check that it is on. If it is, it means the usb stick has a problem.
It's about hard disk usage... utorrent is battering the hard disk saving and serving files, the usb stick writes buffers to the hard drive... so having video acceleration wouldn't make much of a difference...
Raid might...

Hmmm, well there's a temporary fix for me anyway, tested earlier, closed EVERYTHING and set the program to record, even minimised it, and it recorded without dropping any frames. i guess i'll just have to do that when i want to watch something...

Just to add to what Noo has already helped you with, if the card does not have its own MPEG encoder/decoder on it (and I don't see one in the specs on this card) then it's going to have a heck of a time recording video if anything else at all is running. Dropped frames like you have are the result. Best cure is to get a card with a hardware MPEG encoder/decoder chip on it then.
