Re: [mythtv-users] Manually enter freq. in database.

I had the same problem as you, so I created an Openoffice spreadsheet that generates the necessary update statements from something like your web page. The idea is that you search the frequency closest to yours in the official list of channels which will give freqid (e.g. 48.250MHz - E2, 55.250MHz - E3, 62.250MHz - E4 etc.) and then calculate finetune = (your freq - official freq) * 16 If you are interested, I can send you the spreadsheet or give all the details if you prefer to use a different tool.

Ok and the channum I can set to what ever I like, depending where I want the channel when zapping in mythfrontend? Yes, as far as I know. The idea is that you search the frequency closest to yours in the official list of channels which will give freqid (e.g. 48.250MHz - E2, 55.250MHz - E3, 62.250MHz - E4 etc.) I think you are getting close to my root (not the user :)) problem(s) now. 1. I don't know exactly what number to put under freqid under channels in my database. If the Danish channel TV2 if running on 175,25MHz will I put in 175,25 | 17525 | 175250 or something else? You would put E5 into freqid because that is the official identifier of the channel that has the standard frequency of 175.25MHz. and then calculate finetune = (your freq - official freq) * 16 Ok in your calculation you use official freq which I think is the one on www.tre-for.dk but your freq is a little hard to find since I haven't been able to find a utility that is able to scan for channels on my PVR 350. I'm probably using the wrong terminology, but by your freq I meant the actual frequency that you want to tune which is what your provider uses, or to be more precise, the frequency that your capture card thinks it is set to when tuned to the channel in question :). And official freq would be the frequency that is the standard frequency for the given freqid. Your provider could use non-standard frequencies which fall between two standard freqs, that's why you have finetune. Anyway, I checked the web page you mentioned and found 13 channels there. For the first 11 of them, set freqid to E and the value under Kanal concatenated (i.e. E2, E3, ... E12) and for the last two channels freqid is SE9 and SE10 respectively. Finetune is 0 for all the channels. Hope this helps :) Tom ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Strange Audio Behavior - Static in One Speaker

Everything is working very well and my system is stable. I can watch TV using the TV Viewer in Redhat FC4 and if I un-mute the line in, audio is flawless. Sound/music also plays flawlessly. So, I have the patch cable from the Hauppauge WinTV Go Plus to the line in of my Diamond Monster Sound audio card. When I run MythTV and select Watch TV, it fires up fine. However, only the right speaker has audio. The left speaker starts having a tiny amount of static. This static then starts getting louder about every second preceded by a small pop sound. Each time, it's as if the volume of the static is doubled until it becomes so loud it just distorts horribly. If I use kmix and slide the balance all the way to the right speaker, I still hear the audio from the TV card fine. If I slide it all the way to the left, it's pure static. Does anyone have ANY suggestions whatsoever? I'm including potential hardware info at the end of this message and if I've forgotten anything, or can include additional information, please let me know. I'm dying to have this working, it's such a sweet application! Thanks in advance for any insight! I think I have a very similar problem to yours except that I have TV audio on the left hand side. I'm still testing my problem and trying to find a solution. My findings so far: - if I unmute line in, audio is perfect with tvtime - if I mute line in, I get sound from the left speaker in myth. However, sound from the right speaker is not simply static, it is recording form the mic! Yes, that's what is happening: left input is line-in, right input is from the mic at the same time! Please check if this is your case, too. I have two mic plugs, one in the front, one on the rear side of the machine, so if you happen to have a similar PC, you might need to also select the correct mic in kmix to check this. - I can reproduce the pop sound getting louder, can't remember which setting influences this in kmix, but by playing around with controls I could easily get rid of this problem. I cannot check this right now, as a longer recording is in progress on my box. - the problem does not seem to be related to myth however: if I eg. record sound from line in with krecord, the same thing happens: the left side is recording from the line input, the right side from the mic. I suspect the problem is that the sound driver is incompatible with the mixer circuit in the integrated sound card. My motherboard is an ASUS A7N8X-X (nforce2 chipset). Recording works perfectly under Windows, at least. I have no idea where to go next, already tried google, without success. But I'm not an expert in Linux...
