hi sub, sorry for the long questions. [Image: smile.gif]

1) when using the skip mode i sometimes get a screen freeze. The only way to resolve this is by reboot MVP and restart the MVP/GBPVR server program.

From reading the logs this is what I have found.

now the bit about    "An attempt was made to move the file pointer before the beginning of the file."

this was caused by pressing the skip button once and there was quite some time left of the film.



2) I'm using a PVR350 with medium record level. when reading the same log i noticed my file is known as mpeg1. I thought it should be mpeg2 ?

here that part of the log

I havn't had a chance to look at the code for the errors you describe above, but some initial observations.

1) This must be some integer overflow thing happening. After 2147483647, an 32bit integer becomes a negative number, which is what you log seems to be confirming.

07/08/2004 00:38:26.596 VERBOSE [31] MVPSetPlaybackPosition() Set position to:2256195317

2) Not sure why this file is being detected as an MPEG1 file. If its really an MPEG2 file, it will stuff up the ability to skip correctly.

I'll try and find some time to look at these tomorrow.

Thanks for pointing that out! I'm sure that accounts for a few peoples skip problems. It was an integer overflow occurring when I was calculating the new position in the file, when it was past the 2GB point in the file. This is corrected for the next release.

I've now added a few very big video files to set of test files on my development machine.

Thanks for the quick response sub, regarding the MPEG1 nameing - I checked the file out in powerdvd and it says its a MPEG2 stream.

I'm happy with that

Yes, That would make sence since I only have skip issues on large files, probably when I skip past the 2GB point. If you have a test release I would be very happy to test it for you.

I can hardly wait, great job!

I must say that after reviewing my log files I have the same issue with the file being recognized as Mpeg1 when it is really an Mpeg 2 recorded with the PVR350.

This sounds like the cure to my skip problems. Can't wait to test the next release. Great stuff.....

The MPEG1 log message was a red-herring. It said MPEG1 in the log when it detected a MPEG2 file. I've changed the message.
