very choppy my TV playback and recording (3 Viewers)

[Mercury0660]

Hi,
I installed RC4 and had 0.1.3.0 before.
with RC4 the TV playback and recording became very choppy.
My card is a Winfast PVR2000 on Celeron 2.0 with 512 mb RAM.
what could it be? I tried several codecs and de-int options.

thx

I'd think the problem is your on board graphics card. If I'm not mistaken, the Radeon 9100 only supports DirectX 8.1 and MP needs a DirectX 9 card to run smoothly. MP 0.1.3.0 used to support overlay, which doesn't use DirectX 9 so that would explain why it ran smooth on that version. However, overlay support was dropped in one of the 0.2 Release Candidates.

but i use VMR9 Renderless in 0.1.3.0 and not overlay. this works...

is DX9 really the problem? please help

It shouldnt be, as a DX8.1 card is fine for MP. It might put some extra load on the cpu but it wont be huge.

Running fuullscreen tv, bring up taskmanager and see what your cpu usage is.
If its consistantly at 100% then i would say graphics could very well be the problem, try using a different video codec to see if you can lower the cpu use and retest.

Hi,

I have a similar problem with 0.2.0 RC3 onwards. 0.1.3.0 and 0.2.0 RC2 are fine. In my case when using RC3 or RC4, Live TV is fine, but with Timeshifting enabled the playback becomes choppy with stutters every few seconds.

I too have a WinFast PVR2000 and a Shuttle PC with ATI 9100 IGP graphics.

It seems I have had the problem since 0.2.0 RC3 when MP began to recognise my card natively (showing as a PVR2000 as opposed to a Generic H/W Encoding Card). I have asked DMAN who confirms that this native support will still be using H/W encoding, and this seems to be the case since during Live TV or Timeshifting CPU usage hovers around 20%, never higher than 25%. However, while Live TV is great, Timeshifting is not.

I'm not sure that it's an Overlay/video card-grunt issue either, since I'm using VMR9 in RC2 without issue (RC2 has no Overlay option). In RC2 full-screen Live TV with Timeshifting flies along. Something has changed in RC3 - perhaps someone with more knowledge of the program could give me a hint as to what is different, and what I might do to get things working ready for the final 0.2.0 release?

Thanks very much.

i get about 70%, no matter which codec I try to use...
