file size or time limit for 3 hour shows?

[photoagent101]

Hi --
I have been using GBPVR for two or three years. It's a great program. I am primarily a Mac guy so don't know how to do logs and stuff, but can try. I just upgraded to 1.1.16 and the new Schedules Direct service. All works well except for one ongoing, repeatable problem:

I try to record American football games, which last three hours. About 90% of the time, the program cuts off at 1.5 hours into the program (exactly 1:34:39 on the last recording). I have quality set to BEST, and the file size of the 1.5 hour program is a bit over 8 Gb. In the earlier versions of GBPVR, a quality setting of BEST resulted in a file size of half that size; in other words, a 3 hour football game would be 8Gb in size. (To be very clear, my files are being cut off halfway through the game and take up about twice the amount of space that they used to.

I will try messing with the quality settings, but wonder if anyone can shed some light on this problem.

Thanks!

What capture device are you using?

Hi --
Dang, I am so impressed with your software and your support. I am embarassed to report that this is almost certainly an issue with Macs and Quicktime. If I play the large files in Quicktime, the show ends at 1.5 hours, and the "get info" windows show that the program is 1.5 hours. However, playing the program with VLC Lan Player gives the full three hours of programming.

If you have a PVR150, it may be the PVR150 timestamp bug: http://forums.nextpvr.com/showthread.php?t=14006

I saw this thread but was not sure exactly what "timestamp bug" meant. I'll give this a try!

It just means that playing back shows recorded on the PVR150 can sometimes report durations shorter than the show really is. It'll also break the ability to seek/skip to other parts of the file during playback. If you have this problem, you'll usually find it'll play the whole file if left along (dont seek/skip).

Check the file duration from a Windows machine. If it shows 3 hours in Windows Media Player then it's not the timestamp bug, and likely just a limitation of your Mac player software.

If your drive is formatted FAT32 I think there is is 4GB file limit.

Hi folks:

Thanks for all your suggestions. I am using a Hauppauge 150, and the problem almost certainly is the timestamp problem. My drive is formatted NTFS. I did not have this problem in the past GBPVR version. All that remains is for me to implement the timestamp fix, which I will do in the coming days.

Thanks!

I did not have this problem in the past GBPVR version.

If you read that timestamp thread you'll see several posts identical to this, where the user was surprised that the problem just started out of the blue after a long period of no problems. This has no relationship to the version of GB-PVR you're using, and people have had the same problem just start on many versions. I think it is more due to something related to I/O happening on your machine, devices sharing interrupts or something similar.
