2.1.5 HDPVR recording don't play.

[mvallevand]

I just noticed on a few HDPVR recording sometimes NPVR doesn't start with the normal ts headers and I can't play it on the PC, I get a black screen. Going back to it gives this trace. I hadn't noticed this before because the PCH plays it okay.

Code:

Looking at the file with a hex editor view attached, I notice a normal header at 0xED and if I remove the bytes before it the file does play.

This patch should stop the creation of any more of these files with crap at the beginning.

Thanks a lot.

Would this affect LiveTV as well? I've had a couple of instances where starting LiveTV is just a black screen.

Yes, possibly.

[smajor]

Yes, possibly.

I'm going try this and see what it does for my client/server woe.

Hopefully it helps.

For the record though, I have been hoping to get back to looking at your client/server issue, but unfortunately more stuff seems to pile up every day, so its sometime hard to find the time I need.

I know how that is. If I continue to have issues, I'll just keep posting replies to my thread. Then you'll have (hopefully) a ton of data to maybe find something.
