Hauppage Nova-t 500 Driver Bug - Page 5

Bernbo · **15th September 2006, 04:05 PM**

Didn't record the actual figures.

Tuner 1 was 60 to 75 with an average across all channels of about 68
Quality was 100 for everything

Tuner 2 didn't pick up a thing. Scanchannels went through all the frq's but it didn't lock onto anything. So no signal or quality readings as it didn't get a thing.

I did see some posts in the 'Problems with Hauppauge nova t 500 tuner' thread but their situation was slightly different.

As far as the card goes, well its a bit sad really that new magic cant service us better. I got a brand new rig built and only had it for 4 days before I had to rip the card out. Now its been gathering dust for over 2 weeks; bit of a waste really.Anyway thats my whinge and a vent for this arfternoon.

Thanks for your reply DTB and VBAP, boy you guys are quick off the mark!!

Hi,

I wanted to post here to give forum members an update on the issues with the Nova 500 product.

As several users have mentioned in this thread there have been two issues with this product recently. The first was a bad batch of cards which had one tuner significantly weaker in sensitivity (or completely dead) than the other. This issue has been resolved and any user experiencing this problem should email tech@newmagic.com.au requesting an RA number to have their card replaced. The typical symptom of this in MCE is to have all of your TV channels scan ok but not be able to view them (as MCE uses one tuner for scanning and the other for viewing) or to not be able to scan any at all. Other users have posted a complete test using ScanChannelsBDA.

The other issue involves reception problems with ABC and SBS in some parts of Melbourne, and a couple of regional areas. The symptoms are occasional stuttering of playback on these services, and a swinging quality reading in ScanChannelBDA's slow scan mode.

This problem has proven difficult to diagnose but New Magic and Hauppauge engineers are working on a solution. We have made good progress on a fix and hope to have a final update in the next week or so. As soon as we have a final solution we will post into this thread.

We thank you for being patient with us,

Regards

Hi Mark.

Thanks for the update. I'm in Canberra and have problems with the ABC as well.

I'm hoping its a driver issue, so I'm keen to load the new drivers when they're available.

Cheers, Banjo

Thanks for the update Mark.

Look forward to hearing your progress in the next week or so.

Cheers

I have two of these dual tuners. And i think one of them may be one from the 1st batches with dodgey second tuners. In order for me to test this i need to use scanbda right?

can i use this program with both dual tuners in? or should i do it one at a time?

what am i looking for in order for it to tell me whether a second tuner is dodgey?

cheers

yes

you can do it either way. With both tuners, scanbda will show 4 tuners called:
Dev1-Path0,
Dev1-Path1,
Dev2-Path0,
Dev2-Path1
With 1 tuner, you will only get Dev1-Path0 & Dev1-Path1 (regardless of which tuner it is).

A significant signal strength difference for each channel between the 2 tuners on the one card. eg if Channel2 is strength 60 on Path0 and strength 58-62 on Path1, it's OK. If it was, say, Strength 60 on Path 0 but 52 on Path1, it's probably bad batch.
Note, sometimes Path0 may be stonger, sometimes Path1 may be stronger.

I hope this makes sense!

thanks vbap

any idea where i download scanbda from? i tried here
nate.dynalias.net/ScanChannelsBDA/ScanChannelsBDA.html

but that sites down

vbap · **21st September 2006, 11:09 PM**

Follow the links from this post !

CordlezToaster · **22nd September 2006, 08:04 PM**

Hey vbap i did the scanbda and from what i can see i think its ok! but im a bit unsure of what to look for and where

All i have to do is scan each device using the australian search, don`t i?

i have attached the logs if someone could please take a look at them and see if im wrong!

there are four log files in the zip.

cheers

According to your logs, you don't have the "differing signal strength" problem that affected an early batch of the cards. ScanBDA is reporting similar signal strength values for each channel across all fours tuners.

Also according to the scan, you are not getting channel 9 at all, and the strength on SBS is low (45), which is is causing quality issues (all <100%).

Your signal strength for 7 and 10 is fine (~65). I'll leave the ABC out of it for now...

The results are the same for both cards (all 4 tuners reporting similar results).

Have you had your signal strength checked by a professional installer? The difference in signal strength between channels on the same card (eg 65 for 7/10, 45 for SBS, 0 for 9) suggests there is a reception issue somewhere (either the antenna or the cabling leading to the socket where you're plugging in your PC).

Have you checked with a set-top box or other tuenr whether you get all channels properly without issue?

Apologies if you've answered these q's before...

CordlezToaster.

Just continuing on from VBAP. Some stations are horizontally polarised and some are vertically.

For example SBS may be horizontal and the rest vertical.

Have you checked that out?

Just an idea.

Hi Banjo,
I don't think that's quite correct (but I'm not an expert!).
Polarisation depends on the transmission tower. From what I have read at DTV, in Melbourne, Mt. Dandenong transmits horizontal while Como transmits vertical.
It could be that Cordlez is getting reception from different towers, but the scanbda frequencies suggest they are all coming from Mt. Dandenong (except 9, which is not received at all).

Banjo · **26th September 2006, 07:52 AM**

Vbap.

I know that in my case in Canberra that the polarisations are different for VHF and UHF. (SBS is the only UHF station)

So, if the UHF aerial isn't correctly aligned, then the signal strength is lower.

Just an idea.

Cheers, Banjo
