Have tried the 2.6.13 kernel with fresh cvs etc, not too hard to get the front end recognized but the tuner is more of a difficult.

There appear to be enough differences between the currently supported td1316 hybrid tuner and the td1316 sihp in the 777 to cause problems.

A copy of the td1316 data sheet would be excellent, if any one has found one?

I made another post here yesterday, don't know what happened to it!!

Anyway, (to recap), it appears that this card is somewhat simmilar to the Pinnacle 300i, they both have the SAA7134 & MT352 chips, but we have the TDA1316 tuner instead of the 9987 (or whatever)..

So, the suggestion from Hartmut Hackmann (Video4Linux mailing list) was to take the Pinnacle 300i code and replace its tuner logic with that of the TDA1316 (which coincidentally he added just the other day).. I'm attempting to do just that, but I don't know enough about tv cards to have much success..
What I've found so far (for those trawling through code it's in saa7134-dvb.c), is that if you change the .dmod_address from "0x3c >> 1" to "0x1e >> 1" it will successfully initiailise the frontend as an MT352 (which I think is what we want).. however beyond that I'm still at a loss..

anyway, now my dmesg looks like: (note it says AverMedia because I've added the card to my copy of saa7134-cards.c)
saa7134[0]: found at 0000:02:04.0, rev: 1, irq: 169, latency: 32, mmio: 0xf3010000

DVB: registering new adapter (saa7134[0]).

anyone understand that "quirk" line??

Looking at my card there's defintely an MT352 on there...
that quirk line sure is a strange one though - have you tried scanning for channels at all?

Oringally i had also planned to buy the 771, but the 777 was the only thing available. I know for HDTV you need a reasonably fast computer, the specs on the 771 say 800Mhz PIII and on the 777 is like 2.4GHz P4, which is a pretty serious stepup. I was wondering if you use the 777 only for SDTV will you still need the extra CPU ooomphf?

edit:
i'm so glad i found this thread! thanks for all the helpful discussion guys! i think once its sorted out, someone will have to do a full writeup..

I've tried scanning for channels, which it attempts to do, but it always fails.. It doesn't give me any kind of useful error other than "tuning failed".. oh well.. more work required

I noticed while using this card in windows that it does indeed need all the CPU you can throw at it.. I'm guessing the requirements in linux will be less, but the "pause/watch live tv" part was chugging along for the first few seconds even on my 3.2ghz P4..

sheesh! well thanks for the tip! was that even in Standard Def?
I guess it's time to track down a 771.. at least it will work straight out of the box... but wheres the fun in that?

It didn't seem to matter what definition the picture was in, I'm *hoping* it was just the software causing the problem.. myth is a bit different in that it's always recording, which might help things..

Has anyone else here attempted to add support for this card?

I'm still playing around with it, but struggling to find enough time to really get into it.. perhaps if we all start asking the Video4Linux guys for some help we can get someone who really knows what they're doing to help us!

(I have been doing just that, and have gotten some good advice, but like I said I'm still stuck)

Sorry, i have an Pinnacle Media Center 300i, i'm a newbie and i don't understand all you explain, please i see the analog tv but the digital tv don't works, can you explain me what i do to make work my digital card, please ???

Thks a lot !!!

Hi virusbcn, I don't have any useful information for your card (other than it does work in linux), the best idea would be to go here: http://linuxtv.org/v4lwiki


To everyone else with the AverMedia 777, does anyone live anywhere near Hamburg? One of the Video4Linux programmers is willing to add support for our card but needs to borrow one for about 2 weeks.. I'm happy to send mine, but I live all the way in Australia (Melbourne)..

Anyway, if anyone out there lives somewhat closer than me and is willing to give up their card for a while, we can finally get this one working..

I can work with him to add the support myself, but it looks like this will be a far easier option..

Please send me a PM or leave a message here if you're willing to help..
