Hi there,

Does anyone has experience with MSI digi vox USB tuner?

I used one with my laptop today(at Sydney), connected an indoor all-band antenna. But after scan all channels, can only got SBS HD, SBS 1,2, and some D44 channels. Never found 9, 7, ABC or 10. And some of the channels I got always come with a "Fail to play your program".

Is that a vox hardware issue or software issue? Maybe antenna not good. But the antenna work fine with my TV.

Anyone can help?

Thanks!

Yup that would be my guess too

I tried to figure out the problem till 3am this moring.

I found it is TWINHAN OEM product, but not MSI design. After replaced TWINHAN driver, It can watch all SBS and D44 channels now. But still can not get any other channels. And I noticed all the channels I got are UHF band, none VHF channel found. Checked from Internet, 7,10,abc,9 should at VHF band. If the antenna is OK, so why it happened?

Does anyone can recommend another brand with no this problem?

Thanks!

TwinHan has one of the better ranges of DVB products

Given your VHF / UHF issues it may well be that you need to install the drivers with the fixed bandwidth operation option ~ Although it usually manifests itself the other way around with VHF working and UHF failing...

What version of windows ? SP ?

AFAIK you haven't proven that the antenna system is 'good' for digital tv (which are obviously on different channels than the analog ones)

Thanks!

I am using winXP +SP2. Is there a bandwith fixed patch? I got latest driver from TWINHAN web.

How about V-Stream. Is it work fine?

Cheers!

You shouldn't need it for SP2. It's not a patch, just a setting in the driver inf file that you need to change before installing them.

No I would avoid it.

If you want a USB product that has been tested in Australia and is supported in Australia ( and is also a TwinHan OEM product ) get the tinyUSB from http://www.digitalnow.com.au/

But at this stage I think you really need to investigate your antenna system first...

Thanks joeybloggs, they are all really OEM from Twinhan, same shape. I tried the TinyUSB driver too, can recon the box, but still not work on VHF. even the latest version myTheatre not work either.

It looks I have to return it if noone can help more.


Thanks!

I am sorry to disappoint you, but our software does not work with that device.

All,

I actually have the oposite problem using the tinyusb receiver

I can receive VHF but NOT UHF in melbourne using MCE

by the way where did you get the twinhan OEM drivers?

I know its not the antenna etc because i also have a fusion HDTV card which works fine using MCE

I suspect the driver

Hi Strangecity,

The driver of the tinyUSB2 as available here
http://www.digitalnow.com.au/downloads.html

Works perfectly well with MCE, as also reported here
http://www.xpmediacentre.com.au/community/...read.php?t=2223

Try using the tinyMonitor to check the signal stats and help you tune your aerial.

If you can't tune a channel with MCE, it has nothing to do with the driver.

It is either your reception or MCE.

Renura,

I have used tinyMonitor to check the signal stats
Can manual tune all Mt Dandenong & South Yarra Como transmitters

Using Tinymonitor The South Yarra Como UHF Channels can be tuned in and have a much stonger signal strength than Mt dandenong (mainly VHF). But when I attempt to tune using MCE it only tunes in the VHF channels

Its like the UHF signals are filtered out

If I tune just the Dvico tuner (my other tuner in MCE) it picks up all services
when I try to tune just the tinyUSB2 card I just get VHF channels which is not great reception in my area

using XP MCE SP2 with all the updates and patches

Well there you are, there is nothig wrong with the drivers or the device.

Perhaps MCE is tuning in different frequencies and missing out on the ones you need. The tinyMonitor, MC and DNTV Live! and indeed any other application is using the same BDA drivers, so the issues is really with Media Center.

I suggest you head along to the MCE forum and see if someone can help you with the Psidec.dll file that has the freqencies you want for your area.

Also make sure that you are using the drivers for the tinyUSB device from our web site (version 1.0.3.7) and nothing else.

Cheers

All,

I Finally managed to solve this problem after many hours of frustration

Turns out to was a driver issue AND an MCE issue !

solved it by doing the following:

1. used a custom Psidec.dll (thanks to Arkay at Australian media centre community forum for the Dll) that allowed me to tune into only the UHF strong channels which then helped me troubleshoot the issue futher

2. I had to force the tinyUSB driver into 7mhz mode by modifying (uncommenting) the following lines in the UDTT2BDA.inf driver file

;HKR,"DriverData","FixedBandwidth",0x00010001, 0x06,0x00,0x00,0x00
; //Fixed 7 MHz

; //Don't scan +-167KHz, just return lock failure
;HKR,"DriverData","ShiftFreqScan",0x00010001, 0x01,0x00,0x00,0x00

I solved this by looking at the MSI VOX BDA driver inf file for an Australian MCE

Hopefully this may help others with the similar problems !

Renura,

It might be worth modifying your driver to reflect this

Sorry guys,

It has been pointed out that I pasted the wrong line out of the UDTT2BDA.inf file

You need to change
HKR,"DriverData","FixedBandwidth",0x00010001, 0x00,0x00,0x00,0x00
to
HKR,"DriverData","FixedBandwidth",0x00010001, 0x07,0x00,0x00,0x00

and

HKR,"DriverData","ShiftFreqScan",0x00010001, 0x00,0x00,0x00,0x00

To

HKR,"DriverData","ShiftFreqScan",0x00010001, 0x01,0x00,0x00,0x00


you might also need to scan for additional services as MCE may not pick up all the services at once

Also reboot after retuning and doing any driver changes
