Arcsoft Broadcom version of TotalMedia

Comfirmed working in WiFi slot of AOA150 with Arcsoft application and driver above.

Comfirmed working in Windows 7 Media Center when "Broadcom Video Decoder" is selected as the default video codec with the "Media Center Decoder Utility" (MCDU) tool by Gary Whittaker.

Comfirmed working as Video decoder for HiDef ATSC live TV using an internal Pinnacle 80e (HD Mini Stick) tuner
Installed "Direct Show Filter Mangaer", increased "Broadcom Video Decoder" merit value from "Do Not Use" to "Normal".
Installed DvbViewer Pro ($15.00) Any directshow TV program should work provided you can select Broadcom Video Decoder. (Except WatchTV, which has a pixelation breakup problem).
Selected "Broadcom Video Decoder" as Video codec.
De-selected "Use new tuning method", scan for channels.
HD live TV without dropped frames at 40% CPU.

crap... i left my netbook at home today... that sounds like an AWESOME option..... it makes media center 100% more useful!

 

using mdcu on win7 gives me a media center crash when tuning live video.

but using a hauppauge 950q, i get smooth video already.... it could just be the difference in tuners (pinnacle's usb stuff tends to be more dependant on the cpu in my experience)

 

Win 7 Media Center crashes for me also on live TV. Scans channels in setup just fine but when it goes to build the playback graph for live TV it crashes. I tried to switch back to the Microsoft codec being set as default with MDCU, but it still crashes. I may have to reinstall Win 7 to try again.

I have many different USB TV tuners. While most of the video from the tuners are smooth, they all appear to get jerky with high bit rate 1080. The Broadcom card fixes that problem while lowering the CPU from 80% back down to 38%.

On a different note - Could not get my third add-in mPCIe slot to work. Used a 881u mPCIe adapter wired in the 6 PCI bus wires from the daughter board connector, 5 volt power and ground. and slot does not show up at all. I know the 1.5 volt power is missing but I decided to give up on adding the third mPCIe slot. I bought an internal USB wifi board so the Broadcom card can stay in the WiFi slot.

Also - Came up with a Kick A$$ "Touchscreen Internal Stylus Holder" modification. I am doing my second Stylus installation now and should post instructions and pictures soon.

 

i get the graph, and on a station with no signal it's fine (no signal error), but the second i hear the audio kick in.... BAM, crash.

Broadcom should release a reference driver, so this card can be standardized.

also, considering touchscreen here.... after playing with a school bus yellow dell mini (ugly as hell, and thick, but it comes with a built in touchscreen)

lastly, you may know... do any of the touchscreens support multi-touch in windows 7?

 

Not that I know of.

 

Touchscreens are different from "Multi -Touch" screens. Touchscreen panels take one finger / stylus input only at a time whereas Multitouch as teh name suggests takes multiple. I am not sure of a multi touch enabled screen for the AOA.

I was trying to wire in a full PCI bus Mini PCIe slot. USB was not the problem, it was the PCI bus connections. The idea was to use the slot for a Broadcom Decoder card.

I was using the daughter board harness for the wires, they are not shielded. I never wired the 1.5 volt source, so that must have been the problem. I would have taken the 1.5 volts from the 3G connector, but I have moved on to other projects.

Has anyone else got the Broadcom Crystal HD card with a tv turner? if so how?

 

The card installs a Directshow filter with a merit value of "Do not use", once you increase the merit value to "Normal". The card's directshow filter will be available by any program which can use directshow filters. Simply pick a TV program which allows you to change the Directshow filter for video. DVBviewer is just one program which allows you to select Video directshow filters and also works with most hardware. These are the step by step instructions.

1) Installed "Direct Show Filter Mangaer", increased "Broadcom Video Decoder" merit value from "Do Not Use" to "Normal".
2) Installed DvbViewer Pro ($15.00) Any directshow TV program should work provided you can select Broadcom Video Decoder. (Except WatchTV, which has a pixelation breakup problem).
3) Selected "Broadcom Video Decoder" as Video codec.
4) De-selected "Use new tuning method", scan for channels.
5) HD live TV without dropped frames at 40% CPU.

 

Most of the tv programs in my country are in mgeg2 so will this method still work?

 

The card does not seem to accelerate mpeg2 files. so I don't know.

 

Ok, I did all this. But DvbView Pro always crashes when the broadcom decoder is selected. Did you get this problem? Which version of DvbViewer you using? Also the Brodcom drivers your using are they straight from the hp web site?

 

No, try the Arcsoft application. Try building a graph in Graphedit with broadcom decoder. Did you change the merit value?

Whatever version was available a couple of months ago, he has older version in the download section.

Yes

 

Arcsoft theater works perfect for hd playback. Yes I change the merit value to normal. The error is retlated to this ModName: bcmdfilterns.dll. Do you know how I can fix this?
