Mythtv Global TV Terminator

The most recent issue I have been having is getting my analog tv tuners to work. I have a Wintv-hvr-950, and a kworld global tv terminator. I have used my wintv-hvr-950 in the past in a mythbuntu box to record and watch ota atsc broadcasts. I also have struggled (yet never succeeded) to get my global tv terminator to work. Now, I am planning on bringing my computer to my college dorm so I can hook it up to the cable there, and record tv. Unfortunately, cable is an analog signal, so I attempted to use either of my tuners in analog mode (they both support this).

I had a lot of trouble getting sound with my wintv-hvr-950, and decided to try to get my kworld global tv terminator to work. I struggled with this for a while, sometimes getting audio to work, but the audio was playing back too fast, and it sounded like chipmunks were talking. Obviously, this was unwatchable.

I then remembered that I had a cable with the tuner that had audio out. I decided to hook this up to the line-in on my sound card. I set the correct options in mythtv, and eventually got this to work. No matter what I did, this audio also sounded aweful. It wasn’t playing back too fast, but there were popping noises, and clipping. Eventually, I decided to go back, and try using the tuner without the line-in, since that was not giving good quality.

I set the audio device in the backend back to /dev/dsp1, and then proceeded to play around with the sampling rate in the frontend:

setup/setup/TV Settings/Recording Profiles/software encoders/live tv

I eventually got 32000 to work for the sampling rate, and no one sounded like chipmunks anymore!

I edited /etc/modprobe.d/saa7134 to

options saa7134 card=65 tuner=54

for the Kworld Global TV Terminator in ubuntu/mythbuntu.

I am not going to go into how to get this card working because there are other sites out there that do a much better job at explaining how to setup/use this card. Just search through the ubuntu forums for help getting it setup in ubuntu/mythbuntu.
