I welcome comments on the following... I have to say that after all of the hoops I've been jumping through (trying to get my PVR-500 Samsung) tuner card working, I finally broke down and bought a PVR-150 MCE on the way home last night. Since there aren't any driver issues for the PVR-150 in ivtv-0.4-[2,3,4], I went ahead and installed using Knoppmyth R5B7. I now have what I would call a good to very good picture. For the fact that during development (build-up) of my Mythtv box I'm using my DirecTV satellite feed I feel the picture quality is quite good.
Note that the following flow is being buffered and processed both by the existing Tivo and the Mythtv box. I have to be loosing some quality here. Satellite Dish ---> DirecTV Tivo (SAT-T60) ---S-Video---> Mythtv (PVR-150) ---> S-Video ---> Sony 42" HD TV Long story short, it appears that there are issues for the PVR-500 Samsung on Knoppmyth R5B7. I've been told, R5A30 works with an upgrade to ivtv-0.4.3 (ivtv-0.4.4 didn't work for me). The ivtv download site was down last night, so I can't confirm. Follow on - I've noticed a slight buzz on the audio occasionally when I select Watch TV. If I Escape back to the menu, and then select Watch TV a second time, it goes away. Haven't even researched it yet. To Do's... Configure IR Reciever and Blaster Configure PVR-150 MCE remote (new one) Decide on files ystem for second drive (WD SATA - 250G) Leaning towards XFS. Get PVR-500 working for three inputs. Would like to have... Install Mythtv on XBox What fun we are having!

I have a quite long (but shielded, as far as i know), and if i plug it in, i am acctually able to recive NRK (public broadcast television). The quality then isn't great, but with using the cable as an antenna? I would suggest trying the card in another computer. It might be some component inside your computer that is making a lot of noice. > Otoh, ive had some troubles with poor colours on recordings made from composite. I am digitizing some olde Hi8 tapes, connecting the camcorder to the cards composite port. But the images are almost B/W, at least untill i turned up briteness and saturision on my DVD player. On the camcorder the colour quality is OK. I haven't yet decided if it was due to the dvd player using wrong settings or the recording using poor settings, but i will find out - suspect it is a combination... Just got to find time to borrow someones DVD player/TV set and test :) > man, 17.04.2006 kl. 14.00 skrev Michael Horn: > >> I understand that using the s-video in would certainly improve my picture quality, but for the moment, all I'm after is a picture that can >> match that of the tuner in my $30 vcr. >> Since my original post I have made a lot of progress with quality tweaking the fine tuning, brightness, contrast etc, but the biggest problem of the interference present on many channels is still there.

Im currently working on fine tuning the channel frequencies a bit, but thought Id see if there were any other suggestions. Im actually away from that box at the moment, but if needed I can post config filed/dmesg output etc later. I will add tho that my 150 had one of the TCL tuners that was detected as type 4, and that I got working forcing type 50 instead. (and have had very similar results forcing other types including 39, 49 and 56) >>>> Thanks in advance for any help >>>> Michael Horn >>>> ------------------------------------------------------------------------ _______________________________________________ >>>> ivtv-users mailing list >>>> [email protected] >>>> http://ivtvdriver.org/mailman/listinfo/ivtv-users >>>> >>>> >>> _______________________________________________ >>> ivtv-users mailing list >>> [email protected] >>> http://ivtvdriver.org/mailman/listinfo/ivtv-users >>> >>> >> _______________________________________________ >> ivtv-users mailing list >> [email protected] >> http://ivtvdriver.org/mailman/listinfo/ivtv-users >> > _______________________________________________ > ivtv-users mailing list > [email protected] > http://ivtvdriver.org/mailman/listinfo/ivtv-users > _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
