Here is what I did to get this card working (keep in mind that things might be different with the 2.6 kernel and modprobe.conf): Here are the configuration for files I used to get everything working on boot. Please note that these are ADDED to the files, not the entire files. /etc/modules.conf alias char-major-81 bttv options bttv card=1 autoload=0 radio=0 post-install bttv insmod tuner type=2 This cam from the following site: http://www.linuxlogin.com/linux/ati_tv.php Also on the subject of performance, the TV Wonder cards use software encoding. Basically you should be able to record or watch your recording fine with the 733 but not at the same time. This is because your processor has to both encode (record) and decode (play) the video. A hardware encoder like the PVR 250 would be a better idea for that processor (or a faster processor, though the 250 has better image quality as well). -- I probably still have a few (well, now a whole bunch) gmail invites.

Re: [mythtv-users] Bad Tuner? Ati TV Wonder VE
I had this same problem with that card. Make sure you get all the bttv settings correct in your modprobe.conf file. I believe that the cardtype is 64 and tuner is 2 I hope this helps Rick Eric Hattemer wrote: Daniel L. Appleget wrote: I have an ATI TV Wonder VE for my capture card.

I have the current build of KnoppMyth (5A10) and a P3 733 with 512Mb ram. The problem is that bt878 and tuner are picking the wrong tuner. You will have to use the tuner= or card= kernel parameters for that card. After that it will go into the correct tuning automatically. Mandrake has a control panel for that. Otherwise, its kind of tricky because they changed the parameters recently. Try modprobe tuner type=2 modprobe bttv gbuffers=4 See how that works. Otherwise you need to figure out what parameters are right. If it tells you to use card=, I think its a card=64. Another unrelated easy question I had for the experienced. Do I need a faster video card for live TV, if I run the front end and back end on the same box? Do I need a more powerful capture card for live TV, if I run the front end and back end on the same box? Because Live TV is very choppy. Use gkrellm to see what cpu % you are using when just recording. See what % it is when you are watching TV (in a window). If the % jumps, your display is probably too dependent on the cpu. Make sure you are using an accelerated driver for your graphics card. -Eric Hattemer ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] Bad Tuner? Ati TV Wonder VE
I have an ATI TV Wonder VE for my capture card. The tuning seems to be way off i.e. if I set it to channel 22 I see channel 20. I do have the setting right for the tuning types NTSC and USCable.
