hello,
i downloaded tvtime and tried to use it. i found this
bug and i think i found a solution to it. so here it is:
Bug present in tvtime 0.9.15.tar.gz release.
System was Fedora Core 2 on a p4 PC.
Tuner is a cx8800 Leadtek WinFast 2000XP.
in videoimput.c at line 1284 there is the function
videoimput_get_tuner_freq. the following modification
hast to be done in order to correct the bug:
int videoinput_get_tuner_freq( videoinput_t *vidin )
{
if( vidin->hastuner ) {
unsigned long frequency;
if( vidin->isv4l2 ) {
struct v4l2_frequency freqinfo;
/* the following two statements must be added */
freqinfo.tuner = vidin->tunerid;
freqinfo.type = V4L2_TUNER_ANALOG_TV;
/* end of add */
if( ioctl( vidin->grab_fd,
VIDIOC_G_FREQUENCY, &freqinfo ) < 0 ) {
the bug appeared because the tvtime uses v4l2 which
requires the initialization of at least two parameters
before calling ioctl function. these are tuner id and type.
in the original function these parameters were left
uninitialized.
thank you,
iulian

I'm the proud owner of a new pcHDTV-3000 card, running
0.9.15, and I'm also seeing this error after rebuilding and
installing the most recent cx88** drivers:
videoinput: Tuner refuses to tell us the current frequency:

I have also seen it call the tuner a type 46, which also works.
But ungrading a kernel is a nightmare. For 2.6.11, only
composite inputs, 4 of them, are available, no rf can be
found but that may be erronious entries in my modprobe.conf.
If anyone has that sorted, I appreciate a Cc:

The card is a Hauppauge WinTV Go, I'm running Fedora Core 3
and using v4l-info it reports as:

Yeah, I suck. I posted a 0.99 release from HEAD and I'll
leave that there until I finish the diag port which I want
to do for 1.0.
