Is my computer too slow? Choppy video AMD X2 64 4200+

[FenceMan]

Hi guys,

I have an AMD X2 64 4200+ dual core processor with 1 GB of RAM. My video card is an ATI Radeon X1300. My DVB card is a Twinhan 1020a. I have everything set up and channels scanned (110 and 119), but I cannot get a quality picture, the video and audio is choppy and stutters. I have tried the following codecs to no avail:

NVIDIA Purevideo
Elecard 3.0
Intervideo
Cyberlink
ffdshow

The CPU monitor shows hardly any use. I have also tried changing from prevent usage of more than one cpu and back (complete with restarting). Some combinations work better than others, but none works well. Is it possible that this computer is just too slow? If I use my Nexus-S with MyTheater all works fine, but I have been dying to get DD up and running. Can anyone offer any suggestions? Thank you very much.

Note I am using the Twinhan 2.42 drivers and the card is setup as Twinhan Direct under devices.

I have also tried to change the affinity in Windows to force the program to use only one CPU....

Sometimes I have similar problem at Athlon 64 3200+, 1GB RAM, Geforce 6600, Windows XP Pro, MSI MegaSky 580 as BDA device.

Interesting is that video recorded during stuttering is not stuttered when I'm replaying it. Reset Directshow filters from DD menu seems to help for few seconds.

I have my Twinhan setup as WDM, should I try it as BDA?

Perhaps.

This is a known bug with timeshift. Perhaps it's the similar bug.

DD seems to have problems with Athlon X2.

I know there is a XP Update patch for AMD X2 processor, perhaps it could help ?!?

Here are a couple of suggestions. One or more might help:

1) Make sure that prevent using more than one CPU options is enabled.
2) In video options change the rendered to Video Mixing Renderer (NOT 9)
3) Get a faster video card. x1300 is really slow - In video mode the 3d engine is used for video processing so a slow 3d card will have a worse video performance. NVidia is actually publishing a comparison chart of all their cards: http://www.nvidia.com/page/purevideo_support.html. Notice how more powerful 3d engines have more power to process video. Too bad ATI doesn't publish such a chart.

I can certainly try an new video card, but here is what I dont understand:

1. With my current system I can play 720p / 1080i HDTV and the 1080p WMV videos available from Microsoft.

2. I can use my Nexus-S card in software mode with MyTheater and all works fine.

If my system is fast enough for these, why would I need to upgrade video card?

[dmz01]

Do you get 30fps with your card on 1080i content? Drop a 1080i video (not film) mpeg2 onto graphedt (or any other program that allows you to see frame rate of the renderer) and see what kind of fps do you get. I had x600 that would only go up to 21-22 fps hence choppy video. I've upgraded to x1800, no issues since including DvbDream.

Remember that with x1300 you do both - MEPG2 decoding and video deinterlacing in hardware. Try disabling hardware acceleration in your NVidia decoder. Let the CPU do MPEG2 decoding and see if it makes a difference.

I will try that, I am curious. When you say video not film do you mean a TV show instead of say Star Wars Ep III?

[FenceMan]

I am getting no dropped frames with .ts file of Star Wars EP III as well as a .ts file of Numbers from CBS, both encoded at 1080i with 5.1 surround. Is there something else I should try to test?

Did this issue happens only with HD or also with SD ?

As I've previously written, DD does not run very fine on DualCore CPU, I have the same problem with DD and HD H.264 Video on my Pentium 2 x 2.8 Ghz (DVB Viewer works fine with such incoming stream)

[FenceMan]

Not even trying HD channels via DVB, only SD.

[FredB]

I had the same problem on SD channels yesterday with my DualCore, after few minutes video became stuttering... I really don't know where it comes from (Timeshift is disable - Allow only one CPU is enable - etc...)

[Gldansky]

I had EXACTLY the same problems, through my hardware is slightly different.

as I assume, your card may be not the original twinhan card, but generic clone, produced by chinese guys. I have such one, and was facing same problems you've described. Here's how I solve it.

Tried a lot of drivers from twinhan, but none helped. So as last chance, I've downloaded TwinhanDTV 2.65 Build 01-02. Installed it. It installed own drivers, and now problems are gone (for SD). For HD I still have that problem, but since Luxe TV isn't worth of watching anyway, I'm not that worried.
