I have mythtv 0.20.2 running under ubuntu feisty with a single DVICO FusionHDTV 5 RT Lite PCI card. Previously, I had MCE 2005 on the machine, but after a few years of reliable service, it finally hosed itself beyond repair. It is the last Microsoft OS I have in the house, and after playing around with MythMusic, MythDVD, MythVideo, and MythGame, I'm looking forward to the rest of MythTV but have a few questions on TV specific stuff:
1. First, hardware questions. I get SD channels ok, but don't get any HD channels. I have both the analog and ATSC tuners on the card setup as follows:
Card type: Analog V4L capture card
Video device: /dev/video0
Probed info: BT878 video (DViCO FusionHDTV 5 [bttv]
VBI device: /dev/vbi0
Audio device: /dev/dsp
Audio sampling rate limit: (None) and Do not adjust volume (unchecked)
Default input: Television
-and-
Card type: pcHDTV DTV capture card (w/V4L drivers)
Video device: /dev/video0
Probed info: BT878 video (DViCO FusionHDTV 5 [bttv]
Signal Timeout: 1000
Tuning Timeout: 3000
Default input: Television
I don't think it is a signal issue, because I was getting the HD channels fine under MCE and nothing has changed.
I do notice in the log file that when it attempts to scan for channels or access the HDTV tuner, I get the following in the log file:
pcHDTV::GetSignal_v4l1(fd 19, input 2, v4l2): error(Invalid argument)
What does this signify? I read somewhere on mythtv.org that this particularly DVICO card should be configured as a DVB DTV card rather than pcHDTV but when I try that, the UI shows:
Frontend ID: Could not open card #0 Subtype: No such file or directory.
Also, I'm not getting any sound on the SD channels - is there a special setting in the ALSA mixer to fix this? I read somewhere you need to connect the card to your MB with a cable, but as this was not necessary with MCE, I fail to understand why it would be with Linux. I can probably figure this one out - just need to play with it.
2. I signed up with Schedules Direct and created my lineup for my zipcode, and when I look at it on their website under Edit Subscribed Channels, all the channels show up. However, when I look in the channels table, only the SD channels are their. Do the channels in the DB not get populated until they scan? Also, do I need to setup two lineups - one with just SD channels for the SD tuner and one with just HD channels for the HD tuner? I don't have cable or anything, this is all just OTA.
Thanks, Jeff
