Description Forgotten User nqeDWc8OMK 2007-11-17 15:55:24 UTC 
Using a bt878 tv card:

bttv: driver version 0.9.17 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
bttv0: Bt878 (rev 17) at 0000:00:13.0, irq: 20, latency: 32, mmio: 0xcf000000
bttv0: using: Conceptronic CONTVFMi [card=120,insmod option]
bttv0: gpio: en=00000000, out=00000000 in=007fc0ff [init]
bttv0: using tuner=38
bttv0: i2c: checking for MSP34xx @ 0x80... not found
bttv0: i2c: checking for TDA9875 @ 0xb0... not found
bttv0: i2c: checking for TDA7432 @ 0x8a... not found
bttv0: i2c: checking for TDA9887 @ 0x86... not found
bttv0: registered device video0
bttv0: registered device vbi0
bttv0: registered device radio0
bttv0: PLL: 28636363 => 35468950 .. ok
input: bttv IR (card=120) as /class/input/input5

with kdetv, the video shows in slow motion and sometimes it freeze. After a short while, kdetv crash saying something about v4l2 (I couldn't reproduce the crash in this moment)

The slow motion and freeze just happen in 'TV mode' option, 'Normal' and 'Full Screen' works fine, although I'm not sure if the crash also happens on this mode only.

I will attach the crash backtrace after I find out the way to crash it.

Meanwhile I'm attaching the backtrace of the slow motion issue and a lot of related messages from dmesg.

This behavior doesn't happen on 10.2.

does it work better with "xawtv" (the application) or do you run into the same slow motion issue there?
Comment 4 Forgotten User nqeDWc8OMK 2007-11-21 00:45:42 UTC 
Sorry, I can't get xawtv to work.

fyi tvtime works fine.
Comment 5 Jakub Rusinek 2008-05-29 17:31:58 UTC 
tvtime is currently one of the best tv viewers.

almost all are unmaintained, but tvtime has no EOL-like UI and needs no EOL-like components, like xawtv does (DGA or Motif for example).
Comment 6 Lubos Lunak 2009-02-05 17:07:16 UTC 
Kdetv hasn't seen upstream development for ages. I suggest you use another
application if it doesn't work for you.
