I accidentally fixed my “fonts are too small” problem. While reading the MythTV development notes<\/a>, there was mention of everything being designed for a 100dpi screen resolution. As it turns out, my Xorg config was defaulting to 75dpi, so I forced it with the DisplaySize option. Since my video card uses 640×480 for it’s NTSC output, I had to modify the recommended settings to use:<\/p>\n

DisplaySize 162 121 # 100 DPI @ 640×480<\/p><\/blockquote>\n

I was surprised to discover that this solved my font size issues. I had so totally given up on the font size problem I didn’t even list it was a problem in the prior MythTV blog entry. :) I was actually expecting fonts to get even smaller, but I guess this changes how font selection is done, and as a result, everything appears sane now. Neato!<\/p>\n

Also yesterday, in the hopes of reducing the effects of the “crappy audio” problem, and allowing multiple programs to have the soundcard open, I figured out how to get ALSA working natively within MythTV. In the MythTV configurations, the sound device should be “ALSA:default” instead of “\/dev\/dsp”, and the mixer should be “default” instead of “\/dev\/mixer”. The start of this was gleaned from the link I mentioned earlier<\/a>. Mixer settings were found through trial and error. Strangely, MythMusic had a separate playback configuration, so I had to change that to “ALSA:default” as well.<\/p>\n

Now that ALSA is being used, the audio choppiness has not returned. I can still get desync’d A\/V, but I think that’s entirely due to disk latency issues, or something like that. Usually when it happens, if I pause or restart playback, it goes away. Also, since multiple programs can open the ALSA device and play sounds at the same time (thank you ALSA dmix), I can start looking at how to add a tool to play “button press notification” sounds. I’ll initial probably use something like “ircat” piped to a reader just to get a proof-of-concept. Then I’ll find some hooks in mythfrontend to attach it to instead. Eventually, I was a themeable visual notification. I should probably join the dev list to make sure other folks aren’t already working on this.<\/p>\n

I’ve also found mention of “show type priority bumping”, where “New Episode” can trigger a bump in the priority of a recording. This may be a good step towards recording new Stargates at high priority, but reruns at very low priority. In the priority adjusting tool, I can see the third row for this kind of priority bump, but I can’t find the UI elements to adjust it.<\/p>\n
