0-bytes LiveTV entries

[amlopezalonso@…]

I'm experiencing a lot of duplicated LiveTV program entries in the expiration listings, one of them (out of up to three) being always 0 kB in size. Just a few are normal single entries (greater than zero).

A whole sticky post is devoted to this issue (which seems to span across several MythTV versions) in:

I do not know how to debug/backtrace this particular issue, so suggestions are welcome ;-).

PS: I first noticed this issue after performing a manual DB recovery but it might as well be happening since a while before.

There isn't any one cause of 0-byte recordings; you must look at the log file to see the actual cause of your particular problem.

MrShakeTouchpad? on IRC was experiencing this same issue and found that increasing the tuning and signal timeouts on his capture device using mythtv-setup prevented the issue. (He used 7000/10000 ms for his HDHomeRun.)

Mmmmmmmmmmm. I set those values in my box and they didn't work. It is a Nova-T-500 (dual tuner) based anyways. I'll investigate further. Thank you for your advice.

The Nova-T 500 driver has been riddled with bugs since it first appeared. zero-byte recordings are a particular problem if you have active EIT scanning enabled on both tuners, the driver just can't handled constant use of both tuners with regular channel changes.

I also have a Nova-T 500 and now rarely see failed recordings after disabling active EIT scanning on the second of the two tuners.
