I can burn to native archive format just fine, but when I try to burn a DVD to run in a stand alone player it fails in several different ways depending on the options I select. This appears to be related to using cut lists. Is this a known issue?

When I burn a scheduled recording with cutlist and select a DVD menu with chapters I get an error like this:

Quote:

cannot jump to chapter 2 , only 1 exists

When I burn a scheduled recording with cutlist and select a DVD menu without chapters I get a correctly formatted DVD, but with only the first part of the movie there. The VIDEO_TS file sizes reflect this; when they should be maybe 3 gig, they total less than a gig. Thus it is not a burning error, but a file completion error.

When I burn a manual recording with no cutlist the fps is wrong and I get this error (probably a different bug and not hurting me that bad):

MPEG1/2 does not support 5/1 fps

I hacked a work-around as in this topic:

If I turn off "use cutlist" when burning a normal DVD (not a native archive DVD) from a recording it works ok, even with chapters. I in addition to the hack mentioned above, I found that you must have a cut at the very beginning of the recording to use the cutlist without issue.

Interesting details that sound like they are related follow:

I took a native archive recording of the same program from my girfriend's system

R5F1, 3.0ghz dual core, 512meg ram, HD-5500, jacked up MPEG-4 recording profile. <edit> I do not generally record DVB. I capture the NTSC output of my satellite receiver and record directly to MPEG4.

I imported it, watched it, loaded and edited cutpoints and burned a DVD successfully. The burn included using chapters in the menu and cutpoints, both of which caused problems with the other recording.

This is not an isolated case. This happens with all recordings on my HD-5500 nuv system.

I have found that cutpoints on the MPEG-4 nuv file come in "doubles" but the cutpoints on the MPEG-2 mpg file are "normal". On the nuv file, each cutpoint is a set of two adjacent frames. When you use the Pg-Up or Pd-Dn to jump from cutpoint to cutpoint, you stop at both halves of the double cutpoint. This is even true when you have just loaded the commercial skip into the cutlist with the Z key. It also lists the beginning of the recording as a "single" cutpoint that cannot be deleted. The first cutpoint after the beginning is also a "single" cutpoint. This is true whether I load in the commercial skip list or whether I clear all cutpoints (home key) and insert them manually. Is it possible that some of the scripts are seeing only the commercials rather than only the show? FYI: the good but cut off short recording that I get when I select a DVD without a menu does have the main show on it, not the commercials. The MPEG-2 mpg file does not have any of these quirks. The cutpoints are not doubled, and the beginning of the file is not interpreted as a cutpoint. I have searched for bad cut points in the nuv and found none (other than the beginning being labeled as a cutpoint when editing the cutpoints and the first cutpoint being a "single").

When I made native archives of these recordings to transport them I noticed that the file size of the native archive XML file for the correct recording (pvr-350, mpg, mpeg-2?, 7.0gig) (1,262,279) was almost exactly twice as big as for the incorrect recording (HD-5500, nuv, mpeg-4, 7.4 gig) (628,056).

The last few lines of the good recording xml are:

I have native archives of both the good and bad recordings if anyone can interpret them. I only have 250kbit upload DSL, so uploading the entire nuv or mpg are a bit prohibitive.

System Info follows:
This is running R5F1, on an older dual core 3.0ghz Intel CPU with 512 meg ram. The tightest the swap space ever gets it has maybe 300 meg free. <edit> I really only use the video capture portion of the HD-5500 to record from the video out of my satellite receiver. I do not generally record DVB. I capture directly to MPEG4.

I have plenty CPU, so I encode directly to Mpeg4 and do not transcode.

My Mpeg4 encoding quality is jacked way up (0-2) and I have increased the resolution to 640x480. Encoding bit rate is jacked up to 5mb/s. Scale bitrate, HQ encoding, and 4MV encoding are on. I jacked up the MP3 audio sample rate (44100) and quality (2) too.

This is not a dual core issue because I can take a native archive export over to girfriend's single core system and it does the same thing.

Girlfriend's system is much more stock: R5F1, 1.4ghz Athlon, 512 meg ram, PVR-350 so recordings are 480x480 in default MPEG-2 settings.[/quote]
