i want to record tv broadcasts on my box
how ?
i want it to be suitable for good quality recording of anime series. something like mpeg 4 at 768X576 and good bitrate (about 1 GB / hour). and good audio like 192 mp3
the tv is analog composite video (of high quality - right out of the digital cable box) + stereo audio
video : conexant bt878 (works perfectly with kdetv)
audio : realtek ac97 line in
i want it to be schedule-able so i dont have to start stop it manually. console app i can wrap in a script and add to cron is best. gui app that can schedule stuff and generate automatically filenames is good too

I think you can use mplayer/mencoder with the 'at' command to accomplish this.

You could set up mythtv, but that might be a lot more than what you need. But, it does allow you to watch/record TV as well as listen to music and watch videos and such. It's essentially a media center suite for Linux.

i tried this
mencoder tv:// -tv driver=v4l2:norm=PAL:input=1:amode=0:width=768:height=576:adevice=/dev/dsp:audiorate=32000 -oac lavc -lavcopts acodec=mp2:abitrate=224 -srate 44100 -ovc lavc -lavcopts vcodec=mpeg1video -ofps 25 -of mpeg -endpos 1800 -o temp.mpeg
there is no audio (just silence) with both /dev/dsp and /dev/audio. happens under both kde 3.5 and 4.1. i played with the mixer in the desktop and it does not change anything
i did not figure out how to encode to anything other than mpeg 1. i really dont like its low quality
mythtv is huge overkill

I think tvtime is in the repos.
> Oh sorry - just noticed that doesn't record. I use mythtv, which is pretty awesome but i can see how it would be overkill for your needs.

kaffeine is imho the ultimate app for watching/recording tv if you don't want to use any of those media cemters. you can eg adjust a timer to record your favorite series ...
here are some further info

i liked me-tv (from aur). gtk, very minimal, scheduler, recording in background...

Something pretty basic for cron:
29 11 * * 0 ivtv-tune -c 4 ### If using ivtv-utils.
30 11 * * 0 cat /dev/video0 > /data/downloads/WhatEver.mpg ### Video0 might be different.
30 12 * * 0 killall cat
It seemed to work well until I setup mythtv.
Changing the channel won't work properly if you are connected to a cable box, you either have the cable box change the channel or use lirc.
I can't vouch for the sound quality, but it seemed OK.
