Hi,

I've recently (last couple of months) upgraded from R4V5 to R5A16 with Two avermedia DVB-T 771s as my tuners. In R4V5 I never had the issue that I'm currently experiencing which can best be described as an intermittend refusal of one of the two cards (it isn't one card in particular, just one or the other) to feed data into MythTV. I have some logs below to help explain what I'm seeing.

I'd been noticing that some of my recordings were blank since upgrading to R5A16 (as mentioned, nothing has changed in the hardware deparments except I have a new DVD drive). I would go to watch recordings and see a black preview, with a message in the logs, not enough video to make a thubmnail. I knew that I hadn't seen this in R4V5 but because it only happened 2 or 3 times over a 2 month period, that I must have had a really bad signal for some reason, and I didn't think any more about it. Last night however I had the issue on a show I was hoping to record, and when I went to check how it was going and got the blank recording, I decided to investigate further.

Here is what I have managed to gather with the assistance of the logs below.

This is last nights viewing


seems normal enough. Card #0 seems to get chosen as the first card to record with. Later on "Law and Order" started recording on card #0 without issue (not shown in this message) and then "Ghost in the Shell" was scheduled to start. Here is it's message log



When I went to view the recording later on (it was still technically recording at this stage), this message came up


As I mentioned it was still recording, so when it was due to finish recording the following appeared in the log (after a very large number of no data in 1 second messages)



I then decided to try and watch live TV to work out what was going on. As I mentioend, L&O was still recording, so when I hit the Watch TV menu option, it used card #1 (which had just failed to record GITS). This is what I got.



No luck. Couldn't watch live TV. I gave up and went to bed. Next morning, I fired up Myth to do some research.

Switched on and entered Watch TV. Got the following message.



Then decided to click record to make sure that I could record from watching live TV. Got the following



No problem, it picked up card #0 and used it to start recording, and left me on card #1 watching the same channel. I changed channel and then hit record on another channel, so that both cards would be in use. Got the following.



No problems so far. I stopped both recordings from the Media library screen and started the next test. This time, rather than record from watching TV, I decided to record from the schedule. I fired up the schedule and set two programs that were already part way through showing, to record so that they would record immediately. I got the following.



What you can see from the above is that card #0 locked, but couldn't get a PMT. Card #1 locked and successfully tuned to channel. Now the channels all work, on both cards. What's wierd is that I can't lock this down to either one card or one channel. It's happening on both card #0 and card #1 (card #0 this morning, card #1 last night), and in the above examples, on two different channels (channel 3 last night, channel 2 this morning).

Any thoughts would be appreciated. I've set up the cards to use TS mode (this can be seen in the logs), but I haven't enabled the setting to only access the card when needed, but I can't see a correlation to this function, because the card is accessible, it's just not locking to the signal and supplying data. I'm going to be away for a couple of days, so don't think I'm ignoring you if I can't get back to you before Monday.

Cheers
Simon
