[mythtv-users] trying to watch TV via mythtvfrontend

[Ray Olszewski]

For the most part, we need to wait until you do the required testing. I did 
want to clarify two small matters.

Well ... *nearly" some (valid) channel, anyway. If the frequencies are just 
a bit off, the vidcap card might get passable audio but no interpretable 
video ... like back in the (very) old days of TVs, when you tuned them the 
way you still tune dial radios, before AFT made it easy to hit the exact 
frequency.

Also ... a real wild guess here ... I assume Hungary is a PAL country, but 
might Myth be mis-set to default to NTSC?

Or you all may have unrelated issues ... either Myth, non-Myth, or a mix of 
the two. "TV doesn't display properly" is among the most common problems 
encountered by newcomers, and depending on the details, it can be caused by:

1. hardware driver (bttv or ivtv or whatever) problems.

2. hardware setting errors (wrong frequency table, NTSC v. PAL, wrong tuner 
type, etc.).

3. X problems (usually with XV).

4. Audio problems.

5. Permissions problems (that prevent Myth from creating the ringbuffer, 
for example).

And probably a lot of other things. That's why I described your first 
message as "about as vague as they come" or words to that effect. The 
problem description comes up a lot (not just in the last two days, but in 
any week you'd choose to review) not because there is some single, big-deal 
problem with Myth, but because it is the most apparent symptom of many 
*different* underlying problems.
