I'm using ivtv on a myth box. I have a PVR-350 with tuner type 2. I'm running on FC3, and running Axel's at-bleeding. I have several symptoms:
- Can't tune below Ch 58
- poor video quality on all channels above Ch 58.
- indicated buggy encoder, but I can't decipher the numbers. The encoder and decoder are the ones recommended on <http://ivtv.writeme.ch/tiki-index.php?page=FirmwareVersions> and the version numbers (0x02040024, 0x02040011) don't match anything that I understand. What is that number, relative to the encoder file names or MD5 sums?
It's the internal version number available by issuing the command: strings /lib/modules/ivtv-fw-enc.bin | head -n 1 strings /lib/modules/ivtv-fw-dec.bin | head -n 1
I'm running cable, with an RF amp in line. If I don't have the amp I get NO channels. I have to max it out to even see the ones that I do.
Sounds like you have losses (i.e. from splitters) before the amp. Therefore, when the signal gets to the amp, the signal to noise ratio is very low, so you amplify the noise. The amp should be hooked up as close to the source (i.e. cable TV's entrance to your house) as possible--and especially before any splitters.
I have tried ivtv 0.1, 0.2, and now 0.3. No joy. I can moderately easily rebuild the box as FC2 if that's needed.
It's very unlikely that it's a software problem.
Can anyone help?
Also, check to make sure you're using the right frequency table (i.e. us-cable or us-cable-hrc), although, it sounds more like a problem from lack of signal...
HTH.
