From IVTV
Got HVR card on Friday and was about to return it Saturday due to no support on Linux/MythTV. Been fighting with MythTV setup all day and found this update much to my delight. Card is detected and worked for a bit but then froze and no signal came back after restart. Noted that system only sees video0 although I have 2 tuners in my system - PVR150 and the HVR1600. dmseg shows ivtv picking up 150(sets it to video1) and cx18 picking up hvr1600(sets it to video0) but mythsetup cannot see pvr150 on video1?

I got it to work! After a whole bunch of trouble messing around with TVtime and Zapping, I was really displeased with the weird blue screen and error messages like "Invalid Argument." Ubuntu was detecting the card but not an actual /dev/video* so that was a little confusing. What I ended up doing was opening up a terminal with "mplayer -vo xv /dev/video0" to open up mplayer and play from the card (HVR-1600). Normaly, this wouldn't work unless I changed channels to a frequency that actually existed (I think) with "ivtv-tune -c <channel> -d /dev/video0". So while 100 didn't work, 70 did!
tvtime
I think it's known that tvtime does not work with the current drivers. Mplayer seems to work well. Kaffeine also works quite well. Vsnine 01:07, 10 April 2008 (CEST)
Audio is seconds behind the video
With the current driver I have successfully brought up video using SageTV, the audio is about two full seconds behind the video however, and does not seem to follow channel changes, it remains with the first selected channel. So far the only way I have found to get the audio to change is rebooting, when it re-initializes it will then play the audio for the channel that is visible.
I also have MythTV installed but have not yet successfully been able to configure it to find the TV card which is a Hauppage 1600.
The Video is clean and looks good, my source is Time Warner cable from Santa Ana, California.

Frequency Drift with Hauppauge HVR-1600 & CX18 Driver
Guys,
Has anybody experienced frequency drift using the HVR-1600's analog NTSC output? Here are the symptons:
We tune to channel 72 which is around 517.250MHz with ivtv-tune:
ivtv-tune -t us-cable -c 72 -d /dev/video0
Sometimes, ivtv-tune reports signal detected, sometimes it doesn't. Sometimes we have to fine tune to a higher/lower frequency like this:
ivtv-tune -t us-cable -f 518.000 -d /dev/video0
This seems to work for a few hours, maybe one day, and then the signal has a lot of noise in it again.
Sometimes, ivtv-tune can't find any signal.
Here are our specs:
Dell PowerEdge 2650 w/ 4GB RAM (2 Dual-Core Xeon 3.2GHz) ATI Radeon XL (Old card but we're multicasting with VLC so it doesn't matter). 2 - Hauppauge HVR-1600 TV Tuner Cards CX18 driver reports firmware version 0.0.71.0 (12/29/2006) for TV cards.
Thanks.
