If you select a stanard resolution and disable lite interface then no need to initialize the registers, you sould be able to see the frame generation as per the configured Vsync and Hsync timings(resolution dependent)

As long as you are fixed for a specific resolution and do not want to change/monitor anything lite interface is not needed, it is optional please go through product guide for more details.

What exactly you mean by initializing, what values are you wrting ?
I think you can try to narrow down the root cause, you read the registers before initializing and after initialiing and find out the differences
Try a set of register at a time and find out which resgiter and what values are effecting, even a wrong polarity of one signal will effect the results

The enable bits will be taken care from the GUI selection if AXI Lite interface is not selected.
Is this issue seen in hardware or simulation.
The core generally requires 3 to 5 frames to get lock,did you simulated this long.

Which version of the core are you using?
Is it EDK based or standalone?
Can you share your core .xco?
I would suggest you to run simulation and send us the dump for investigation

I have enabled both detector and generator. I get the following reg dump. the generator signals are remain same as in the default/constant gui.
The values are
Control Reg (XVTC_CTL) : 0x2F
Status (XVTC_ISR) : 0xB00
Error Status (XVTC_ERROR) : 0x7F0000
Version # : 0x6010006
Dectector Active Size (XVTC_DASIZE) : 0x7970A20
Detector Timing Status(XVTC_DTSTAT) : 0x4
Dectector Encoding (XVTC_DFENC) : 0x0
Detector Polarity (XVTC_DPOL) : 0x13
Dectector H Size (XVTC_DHSIZE) : 0xDA4
Detector V Size (XVTC_DVSIZE) : 0x798
Detector H Sync (XVTC_DHSYNC) : 0xA210A20
Gen. Active Size (XVTC_GASIZE) : 0x2D00500
Gen. Timing Status (XVTC_GTSTAT) : 0x0
Gen. Encoding (XVTC_GFENC) : 0x2
Gen. Polarity (XVTC_GPOL) : 0x7F
Gen H Size (XVTC_GHSIZE) : 0x672
Gen V Size (XVTC_GVSIZE) : 0x2EE02EE
Genr H Sync (XVTC_GHSYNC) : 0x596056E
what could be the problem?
