I read through a thread in the "improvements" forum, hoping to find a definitive answer on how to get QAM set up for my hauppauge hvr-1600, but I'm confused as to whether it actually works or not.

I am running TVServer, using the SVN version 16392 from 10-30-07. I am using the MediaPortal SVN from the same day.

I have set everything else up, and everything is working fine for analog channels.

I am, however, unable to get QAM to work at all. I have my cable plugged into both the analog and digital connections of the hvr-1600.

I am able to tune 5 HD Clear QAM channels using Hauppauge's WinTV6 and using GB-PVR 1.0.16 with no problems.

When I run the tuning for the digital side of the card in TVServer, it goes right through all of the frequencies without finding anything.

I found from WinTV/GBPVR which frequencies my channels are on:
607250 khz - channel 88 (TNT HD)
679250 khz - channel 105 (ABC HD and FOX HD)
673250 khz- channel 104 (NBC HD)
727250 khz- channel 113 (PBS HD and CBS HD)

I also got the following tuning information from GBPVR, but it doesn't make much sense:

NBC HD - T:104,3,1~P:3~V:49~A:52~PMT:48~N:>3.1 WKYC-HD (000(AC3))
ABC HD - T:105,5,1~P:5~V:81~A:84~PMT:80~N:>5.1 WEWS HD (000(AC3))
FOX HD - T:105,8,1~P:8~V:129~A:132~PMT:128~N:>8.1 WJW HD (000(AC3))
WVIZ HD - T:113,113,1~P:1~V:49~A:50~PMT:48~N:>113.1 Unknown1 (000(AC3))
CBS HD - T:113,113,2~P:2~V:33~A:36~PMT:32~N:>113.2 Unknown2 (000(AC3))
TNT HD- T:88,88,1~P:3~V:68~A:72~PMT:71~N:>88.1 Unknown1 (000(AC3))


I tried creating my own .QAM file in the tuningparameters, containing just the 4 frequencies from above, to speed up the scanning for channels. I noticed when it hits these frequencies it says "NOTHING FOUND" but when it scans other frequencies, it says "NO SIGNAL"... so it seems like something different is definitely happening with these frequencies.

I notice the 'physical channel' when scanning for digital channels always seems to be "-1" - I'm wondering if this is part of the problem.

I have also tried adding a channel manually, selecting the ATSC tab, and guessing at the "Channel" "audioPID" "videoPID" etc. based on the GBPVR tuning info above, but as soon as I click OK, all the settings I typed in seem to be lost. If I go back in to the channel I just created and click on ATSC tab agin, it says "no ATSC tuning details available for this channel".


I THEN tried going into the database, and changing values for the channels I created, manually, but this also didnt work.

PLEASE can anyone help me get QAM working? I keep feeling like I'm getting so close.. but then it turns out to be false hope....


Thanks for any help,
Dan
